is for Albert Einstein

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. His mass–energy equivalence formula E = mc, which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect.

Born in the German Empire, Einstein moved to Switzerland in 1895, forsaking his German citizenship (as a subject of the Kingdom of Württemberg) the following year. In 1897, at the age of seventeen, he enrolled in the mathematics and physics teaching diploma program at the Swiss federal polytechnic school in Zurich, graduating in 1900. He acquired Swiss citizenship a year later, which he kept for the rest of his life, and afterwards secured a permanent position at the Swiss Patent Office in Bern. In 1905, he submitted a successful PhD dissertation to the University of Zurich. In 1914, he moved to Berlin to join the Prussian Academy of Sciences and the Humboldt University of Berlin, becoming director of the Kaiser Wilhelm Institute for Physics in 1917; he also became a German citizen again, this time as a subject of the Kingdom of Prussia. 

 In 1933, while Einstein was visiting the United States, Adolf Hitler came to power in Germany. Horrified by the Nazi persecution of his fellow Jews, he decided to remain in the US, and was granted American citizenship in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential German nuclear weapons program and recommending that the US begin similar research.

In 1905, sometimes described as his annus mirabilis (miracle year), he published four groundbreaking papers. In them, he outlined a theory of the photoelectric effect, explained Brownian motion, introduced his special theory of relativity, and demonstrated that if the special theory is correct, mass and energy are equivalent to each other. In 1915, he proposed a general theory of relativity that extended his system of mechanics to incorporate gravitation. A cosmological paper that he published the following year laid out the implications of general relativity for the modeling of the structure and evolution of the universe as a whole. In 1917, Einstein wrote a paper which introduced the concepts of spontaneous emission and stimulated emission, the latter of which is the core mechanism behind the laser and maser, and which contained a trove of information that would be beneficial to developments in physics later on, such as quantum electrodynamics and quantum optics.

In the middle part of his career, Einstein made important contributions to statistical mechanics and quantum theory. Especially notable was his work on the quantum physics of radiation, in which light consists of particles, subsequently called photons. With physicist Satyendra Nath Bose, he laid the groundwork for Bose–Einstein statistics. For much of the last phase of his academic life, Einstein worked on two endeavors that ultimately proved unsuccessful. First, he advocated against quantum theory's introduction of fundamental randomness into science's picture of the world, objecting that God does not play dice. Second, he attempted to devise a unified field theory by generalizing his geometric theory of gravitation to include electromagnetism. As a result, he became increasingly isolated from mainstream modern physics.

is for Benjamin Franklin

Benjamin Franklin (January 17, 1706 [O.S. January 6, 1705] – April 17, 1790) was an American polymath: a writer, scientist, inventor, statesman, diplomat, printer, publisher and political philosopher. Among the most influential intellectuals of his time, Franklin was one of the Founding Fathers of the United States; a drafter and signer of the Declaration of Independence; and the first postmaster general.

Born in the Province of Massachusetts Bay, Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing The Pennsylvania Gazette at age 23. He became wealthy publishing this and Poor Richard's Almanack, which he wrote under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper known for its revolutionary sentiments and criticisms of the policies of the British Parliament and the Crown. He pioneered and was the first president of the Academy and College of Philadelphia, which opened in 1751 and later became the University of Pennsylvania. He organized and was the first secretary of the American Philosophical Society and was elected its president in 1769. He was appointed deputy postmaster-general for the British colonies in 1753, which enabled him to set up the first national communications network.

Franklin was active in community affairs and colonial and state politics, as well as national and international affairs. He became a hero in America when, as an agent in London for several colonies, he spearheaded the repeal of the unpopular Stamp Act by the British Parliament. An accomplished diplomat, he was widely admired as the first U.S. ambassador to France and was a major figure in the development of positive Franco–American relations. His efforts proved vital in securing French aid for the American Revolution. From 1785 to 1788, he served as President of Pennsylvania. At some points in his life, he owned slaves and ran "for sale" ads for slaves in his newspaper, but by the late 1750s, he began arguing against slavery, became an active abolitionist, and promoted the education and integration of African Americans into U.S. society.

As a scientist, Franklin's studies of electricity made him a major figure in the American Enlightenment and the history of physics. He also charted and named the Gulf Stream current. His numerous important inventions include the lightning rod, bifocals, glass harmonica and the Franklin stove. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania. 

 Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity. He was the only person to sign the Declaration of Independence, Treaty of Paris, peace with Britain and the Constitution. Foundational in defining the American ethos, Franklin has been called "the most accomplished American of his age and the most influential in inventing the type of society America would become".

Franklin's life and legacy of scientific and political achievement, and his status as one of America's most influential Founding Fathers, have seen him honored for more than two centuries after his death on the $100 bill and in the names of warships, many towns and counties, educational institutions and corporations, as well as in numerous cultural references and a portrait in the Oval Office. His more than 30,000 letters and documents have been collected in The Papers of Benjamin Franklin. Anne Robert Jacques Turgot said of him: "Eripuit fulmen cœlo, mox sceptra tyrannis" ("He snatched lightning from the sky and the scepter from tyrants").

The United States one-hundred-dollar bill (US$100) is a denomination of United States currency. The first United States Note with this value was issued in 1862 and the Federal Reserve Note version was first produced in 1914. Inventor and U.S. Founding Father Benjamin Franklin has been featured on the obverse of the bill since 1914, which now also contains stylized images of the Declaration of Independence, a quill pen, the Syng inkwell, and the Liberty Bell. The reverse depicts Independence Hall in Philadelphia, which it has featured since 1928.

The $100 bill is the largest denomination that has been printed and circulated since July 13, 1969, when the larger denominations of $500, $1,000, $5,000, and $10,000 were retired. As of December 2018, the average life of a $100 bill in circulation is 22.9 years before it is replaced due to wear.

The bills are also commonly referred to as "Bens", "Benjamins", or "Franklins", in reference to the use of Benjamin Franklin's portrait by the French painter Joseph Duplessis on the denomination, as "C-Notes" or "Century Notes", based on the Roman numeral for 100, or as "blue faces", based on the blue tint of Franklin's face in the current design. The bill is one of two denominations printed today that does not feature a president of the United States, the other being the $10 bill, featuring Alexander Hamilton. The Series 2009 $100 bill redesign was unveiled on April 21, 2010, and was issued to the public on October 8, 2013. The new bill costs

12.6 cents to produce and has a blue ribbon woven into the center of the currency with "100" and Liberty Bells, alternating, that appear when the bill is tilted.

As of June 30, 2012, the $100 bill comprised 77% of all US currency in circulation. Federal Reserve data from 2017 showed that the number of $100 bills exceeded the number of $1 bills. However, a 2018 research paper by the Federal Reserve Bank of Chicago estimated that 80 percent of $100 bills were in other countries. Possible reasons included $100 bills being used as a reserve currency against economic instability that affected other currencies, and use of the bills for criminal activities.

is for Charlie Chaplin

Sir Charles Spencer Chaplin (16 April 1889 – 25 December 1977) was an English comic actor, filmmaker, and composer who rose to fame in the era of silent film. He became a worldwide icon through his screen persona, the Tramp, and is considered one of the film industry's most important figures. His career spanned more than 75 years, from his childhood in the Victorian era until a year before his death in 1977, and encompassed both accolade and controversy.

Chaplin's childhood in London was one of poverty and hardship. His father was absent and his mother struggled financially – he was sent to a workhouse twice before the age of nine. When he was 14, his mother was committed to a mental asylum. Chaplin began performing at an early age, touring music halls and later working as a stage actor and comedian. At 19, he was signed to the Fred Karno company, which took him to the United States. He was scouted for the film industry and began appearing in 1914 for Keystone Studios. He soon introduced and adopted the Tramp as his screen persona. He directed his own films and continued to hone his craft as he moved to Essanay Studios, where the Tramp persona was developed emotionally in The Tramp (1915). 

 He then attracted a large fanbase and demanded more money as he moved to Mutual and First National corporations. By 1918, he was one of the world's best-paid and best-known figures.

In 1919, Chaplin co-founded the distribution company United Artists, which gave him complete control over his films. His first feature-length film was The Kid (1921), followed by A Woman of Paris (1923), The Gold Rush (1925), and The Circus (1928). He initially refused to move to sound films in the 1930s, instead producing City Lights (1931) and Modern Times (1936) without dialogue. His first sound film was The Great Dictator (1940), which satirised Adolf Hitler. The 1940s were marked with controversy for Chaplin, and his popularity declined rapidly. He was accused of communist sympathies, and some members of the press and public were scandalised by his involvement in a paternity suit and marriages to much younger women. An FBI investigation was opened, and Chaplin was forced to leave the U.S. in 1952 and settle in Switzerland. He abandoned the Tramp in his later films, which include Monsieur Verdoux (1947), Limelight (1952), A King in New York (1957), and A Countess from Hong Kong (1967).

Chaplin wrote, directed, produced, edited, starred in, and composed the music for most of his films. He was a perfectionist, and his financial independence enabled him to spend years on the development and production of a picture. His films are characterised by slapstick combined with pathos, typified in the Tramp's struggles against adversity. Many contain social and political themes, as well as autobiographical elements. He received an Honorary Academy Award for "the incalculable effect he has had in making motion pictures the art form of this century" in 1972, as part of a renewed appreciation for his work. He continues to be held in high regard, with The Gold Rush, City Lights, Modern Times, and The Great Dictator often ranked on lists of the greatest films.

is for Doris Day

Doris Day (born Doris Mary Anne Kappelhoff; April 3, 1922 – May 13, 2019) was an American actress and singer. She began her career as a big band singer in 1937, achieving commercial success in 1945 with two No. 1 recordings, "Sentimental Journey" and "My Dreams Are Getting Better All the Time" with Les Brown and His Band of Renown. She left Brown to embark on a solo career and recorded more than 650 songs from 1947 to 1967.

Day was one of the leading Hollywood film stars of the 1950s and 1960s. Her film career began with Romance on the High Seas (1948). 

 She starred in films of many genres, including musicals, comedies, dramas and thrillers. She played the title role in Calamity Jane (1953) and starred in Alfred Hitchcock's The Man Who Knew Too Much (1956) with James Stewart. She co-starred with Rock Hudson in three successful comedies, Pillow Talk (1959), for which she was nominated for the Academy Award for Best Actress, Lover Come Back (1961) and Send Me No Flowers (1964). She also worked with James Garner on both Move Over, Darling (1963) and The Thrill of It All (1963) and starred alongside Clark Gable, Cary Grant, James Cagney, David Niven, Ginger Rogers, Jack Lemmon, Frank Sinatra, Kirk Douglas, Lauren Bacall, and Rod Taylor in various films. After ending her film career in 1968, she starred in her own television sitcom The Doris Day Show (1968–1973).

In 1989, Day was awarded the Golden Globe and the Cecil B. DeMille Award for Lifetime Achievement in Motion Pictures. 

 In 2004, she was awarded the Presidential Medal of Freedom. In 2008, she received the Grammy Lifetime Achievement Award as well as a Legend Award from the Society of Singers. In 2011, she was awarded the Los Angeles Film Critics Association's Career Achievement Award. In 2011, Day released her 29th studio album, My Heart, which contained new material and became a UK Top 10 album. As of 2020, she was one of eight recording artists to have been the top box-office earner in the United States four times.

is for Edgar Allan Poe

Edgar Allan Poe (January 19, 1809 – October 7, 1849) was an American writer, poet, editor, and literary critic who is best known for his poetry and short stories, particularly his tales involving mystery and the macabre. He is widely regarded as one of the central figures of Romanticism and Gothic fiction in the United States and of early American literature. Poe was one of the country's first successful practitioners of the short story, and is generally considered to be the inventor of the detective fiction genre. In addition, he is credited with contributing significantly to the emergence of science fiction. He is the first well-known American writer to earn a living exclusively through writing, which resulted in a financially difficult life and career.

Poe was born in Boston. He was the second child of actors David and Elizabeth "Eliza" Poe. His father abandoned the family in 1810, and when Eliza died the following year, Poe was taken in by John and Frances Allan of Richmond, Virginia. They never formally adopted him, but he lived with them well into young adulthood. Poe attended the University of Virginia but left after only a year due to a lack of money. He frequently quarreled with John Allan over the funds needed to continue his education as well as his gambling debts. In 1827, having enlisted in the United States Army under the assumed name of Edgar A. Perry, he published his first collection, Tamerlane and Other Poems, which was credited only to "a Bostonian". Poe and Allan reached a temporary rapprochement after the death of Allan's wife, Frances, in 1829. However, Poe later failed as an officer cadet at West Point, declared his intention to become a writer, primarily of poems, and parted ways with Allan.

Poe switched his focus to prose and spent the next several years working for literary journals and periodicals, becoming known for his own style of literary criticism. His work forced him to move between several cities, including Baltimore, Philadelphia, and New York City. In 1836, when he was 27, he married his 13-year-old cousin, Virginia Clemm. She died of tuberculosis in 1847.

In January 1845, he published his poem "The Raven" to instant success. He planned for years to produce his own journal, The Penn, later renamed The Stylus. But before it began publishing, Poe died in Baltimore in 1849, aged 40, under mysterious circumstances. The cause of his death remains unknown and has been attributed to many causes, including disease, alcoholism, substance abuse, and suicide.

Poe's works influenced the development of literature throughout the world and even impacted such specialized fields as cosmology and cryptography. Since his death, he and his writings have appeared throughout popular culture in such fields as art, photography, literary allusions, music, motion pictures, and television. Several of his homes are dedicated museums. In addition, The Mystery Writers of America presents an annual Edgar Award for distinguished work in the mystery genre.

is for Francis Bacon

Francis Bacon, 1st Viscount St Alban, 1st Baron Verulam, PC (/ˈbeɪkən/; 22 January 1561 – 9 April 1626) was an English philosopher and statesman who served as Attorney General and Lord Chancellor of England under King James I. Bacon argued for the importance of natural philosophy, guided by the scientific method, and his works remained influential throughout the Scientific Revolution.

Bacon has been called the father of empiricism. He argued for the possibility of scientific knowledge based only upon inductive reasoning and careful observation of events in nature. He believed that science could be achieved by the use of a sceptical and methodical approach whereby scientists aim to avoid misleading themselves. 

Although his most specific proposals about such a method, the Baconian method, did not have long-lasting influence, the general idea of the importance and possibility of a sceptical methodology makes Bacon one of the later founders of the scientific method. His portion of the method based in scepticism was a new rhetorical and theoretical framework for science, whose practical details are still central to debates on science and methodology. He is famous for his role in the scientific revolution, promoting scientific experimentation as a way of glorifying God and fulfilling scripture.

Bacon was a patron of libraries and developed a system for cataloguing books under three categories – history, poetry, and philosophy –  which could further be divided into specific subjects and subheadings. About books he wrote: "Some books are to be tasted; others swallowed; and some few to be chewed and digested." The Baconian theory of Shakespeare authorship, a fringe theory which was first proposed in the mid-19th century, contends that Bacon wrote at least some and possibly all of the plays conventionally attributed to William Shakespeare.

Bacon was educated at Trinity College at the University of Cambridge, where he rigorously followed the medieval curriculum, which was presented largely in Latin. He was the first recipient of the Queen's counsel designation, conferred in 1597 when Elizabeth I reserved him as her legal advisor. After the accession of James I in 1603, Bacon was knighted, then created Baron Verulam in 1618 and Viscount St Alban in 1621. He had no heirs, and so both titles became extinct on his death of pneumonia in 1626 at the age of 65. He is buried at St Michael's Church, St Albans, Hertfordshire.

is for Galileo Galilei

Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei (/ˌɡælɪˈleɪoʊ ˌɡælɪˈleɪ/, US also /ˌɡælɪˈliːoʊ -/; Italian: [ɡaliˈlɛːo ɡaliˈlɛːi]) or mononymously as Galileo, was an Italian astronomer, physicist and engineer, sometimes described as a polymath. He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the father of observational astronomy, modern-era classical physics, the scientific method, and modern science.

Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of the pendulum and "hydrostatic balances". He was one of the earliest Renaissance developers of the thermoscope and the inventor of various military compasses. With an improved telescope he built, he observed the stars of the Milky Way, the phases of Venus, the four largest satellites of Jupiter, Saturn's rings, lunar craters and sunspots. He also built an early microscope.

Galileo's championing of Copernican heliocentrism was met with opposition from within the Catholic Church and from some astronomers. The matter was investigated by the Roman Inquisition in 1615, which concluded that his opinions contradicted accepted Biblical interpretations.

Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack and ridicule Pope Urban VIII, thus alienating both the Pope and the Jesuits, who had both strongly supported Galileo up until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest. During this time, he wrote Two New Sciences (1638), primarily concerning kinematics and the strength of materials.

is for Henry Clay

Henry Clay (April 12, 1777 – June 29, 1852) was an American lawyer and statesman who represented Kentucky in both the U.S. Senate and House of Representatives. He was the seventh House speaker as well as the ninth secretary of state. He unsuccessfully ran for president in the 1824, 1832, and 1844 elections. He helped found both the National Republican Party and the Whig Party. For his role in defusing sectional crises, he earned the appellation of the "Great Compromiser" and was part of the "Great Triumvirate" of Congressmen, alongside fellow Whig Daniel Webster and Democrat John C. Calhoun.

Clay was born in Virginia, in 1777, and began his legal career in Lexington, Kentucky, in 1797. As a member of the Democratic-Republican Party, Clay won election to the Kentucky state legislature in 1803 and to the U.S. House of Representatives in 1810. He was chosen as Speaker of the House in early 1811 and, along with President James Madison, led the United States into the War of 1812 against Great Britain. In 1814, he helped negotiate the Treaty of Ghent, which brought an end to the War of 1812, and then after the war, Clay returned to his position as Speaker of the House and developed the American System, which called for federal infrastructure investments, support for the national bank, and high protective tariff rates. 

In 1820 he helped bring an end to a sectional crisis over slavery by leading the passage of the Missouri Compromise. Clay finished with the fourth-most electoral votes in the multi-candidate 1824-1825 presidential election and used his position as speaker to help John Quincy Adams win the contingent election held to select the president. President Adams then appointed Clay to the prestigious position of secretary of state; as a result, critics alleged that the two had agreed to a "corrupt bargain".

Despite receiving support from Clay and other National Republicans, Adams was defeated by Democrat Andrew Jackson in the 1828 presidential election. Clay won election to the Senate in 1831 and ran as the National Republican nominee in the 1832 presidential election.

 Clay was defeated decisively by President Jackson primarily due to his support for the national bank, which Jackson vehemently opposed. After the 1832 election, Clay helped bring an end to the nullification crisis by leading passage of the Tariff of 1833. During Jackson's second term, opponents of the president including Clay, Webster, and William Henry Harrison created the Whig Party, and through the years, Clay became a leading congressional Whig.

Clay sought the presidency in the 1840 election but was passed over at the Whig National Convention in favor of Harrison. When Harrison died and his vice president John Tyler ascended to office in 1841, Clay clashed with Tyler, who broke with Clay and other congressional Whigs. Clay resigned from the Senate in 1842 and won the 1844 Whig presidential nomination, but he was narrowly defeated in the general election by Democrat James K. Polk, who made the annexation of the Republic of Texas his top issue. Clay strongly criticized the subsequent Mexican–American War and sought the Whig presidential nomination in 1848 but was passed over in favor of General Zachary Taylor who went on to win the election. After returning to the Senate in 1849, Clay played a key role in passing the Compromise of 1850, which postponed a crisis over the status of slavery in the territories. Clay was one of the most important and influential political figures of his era.

is for Isaac Newton

Sir Isaac Newton (/ˈnjuːtən/; 4 January [O.S. 25 December] 1643 – 31 March [O.S. 20 March] 1727) was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author. Newton was a key figure in the Scientific Revolution and the Enlightenment that followed. His book Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), first published in 1687, achieved the first great unification in physics and established classical mechanics. Newton also made seminal contributions to optics, and shares credit with German mathematician Gottfried Wilhelm Leibniz for formulating infinitesimal calculus, though he developed calculus years before Leibniz. He contributed to and refined the scientific method, and his work is considered the most influential in bringing forth modern science.

In the Principia, Newton formulated the laws of motion and universal gravitation that formed the dominant scientific viewpoint for centuries until it was superseded by the theory of relativity. He used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System's heliocentricity. Newton solved the two-body problem, and introduced the three-body problem. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. 

Newton's inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Maupertuis, La Condamine, and others, thereby convincing most European scientists of the superiority of Newtonian mechanics over earlier systems. Newton was also the first to calculate the age of Earth by experiment, and described a precursor to the modern wind tunnel.

Newton built the first reflecting telescope and developed a sophisticated theory of colour based on the observation that a prism separates white light into the colours of the visible spectrum. His work on light was collected in his book Opticks, published in 1704. He originated prisms as beam expanders and multiple-prism arrays, which would later become integral to the development of tunable lasers. He also anticipated wave–particle duality and was the first to theorize the Goos–Hänchen effect. He further formulated an empirical law of cooling, which was the first heat transfer formulation and serves as the formal basis of convective heat transfer, made the first theoretical calculation of the speed of sound, and introduced the notions of a Newtonian fluid and a black body. Furthermore, he made early studies into electricity. In addition to his creation of calculus, Newton's work on mathematics was extensive. He generalized the binomial theorem to any real number, introduced the Puiseux series, was the first to state Bézout's theorem, classified most of the cubic plane curves, contributed to the study of Cremona transformations, developed a method for approximating the roots of a function, and also originated the Newton–Cotes formulas for numerical integration. 

 He further initiated the field of calculus of variations, devised an early form of regression analysis, and was a pioneer of vector analysis.

Newton was a fellow of Trinity College and the second Lucasian Professor of Mathematics at the University of Cambridge; he was appointed at the age of 26. He was a devout but unorthodox Christian who privately rejected the doctrine of the Trinity. He refused to take holy orders in the Church of England, unlike most members of the Cambridge faculty of the day. Beyond his work on the mathematical sciences, Newton dedicated much of his time to the study of alchemy and biblical chronology, but most of his work in those areas remained unpublished until long after his death. Politically and personally tied to the Whig party, Newton served two brief terms as Member of Parliament for the University of Cambridge, in 1689–1690 and 1701–1702. He was knighted by Queen Anne in 1705 and spent the last three decades of his life in London, serving as Warden (1696–1699) and Master (1699–1727) of the Royal Mint, in which he increased the accuracy and security of British coinage, as well as president of the Royal Society (1703–1727).

is for John F. Kennedy

John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), also known as JFK, was the 35th president of the United States, serving from 1961 until his assassination in 1963. He was the first Roman Catholic and youngest person elected president at 43 years. Kennedy served at the height of the Cold War, and the majority of his foreign policy concerned relations with the Soviet Union and Cuba. A member of the Democratic Party, Kennedy represented Massachusetts in both houses of the United States Congress prior to his presidency.

Born into the prominent Kennedy family in Brookline, Massachusetts, Kennedy graduated from Harvard University in 1940, joining the U.S. Naval Reserve the following year. During World War II, he commanded PT boats in the Pacific theater. Kennedy's survival following the sinking of PT-109 and his rescue of his fellow sailors made him a war hero and earned the Navy and Marine Corps Medal, but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate, serving as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. 

 Kennedy ran in the 1960 presidential election. His campaign gained momentum after the first televised presidential debates in American history, and he was elected president, narrowly defeating Republican opponent Richard Nixon, the incumbent vice president.

Kennedy's presidency saw high tensions with communist states in the Cold War. He increased the number of American military advisers in South Vietnam, and the Strategic Hamlet Program began during his presidency. In 1961, he authorized attempts to overthrow the Cuban government of Fidel Castro in the failed Bay of Pigs Invasion and Operation Mongoose. In October 1962, U.S. spy planes discovered Soviet missile bases had been deployed in Cuba. The resulting period of tensions, termed the Cuban Missile Crisis, nearly resulted in nuclear war. In August 1961, after East German troops erected the Berlin Wall, Kennedy sent an army convoy to reassure West Berliners of U.S. support, and delivered one of his most famous speeches in West Berlin in June 1963. In 1963, Kennedy signed the first nuclear weapons treaty. He presided over the establishment of the Peace Corps, Alliance for Progress with Latin America, and the continuation of the Apollo program with the goal of landing a man on the Moon before 1970. He supported the civil rights movement but was only somewhat successful in passing his New Frontier domestic policies.

On November 22, 1963, Kennedy was assassinated in Dallas. His vice president, Lyndon B. Johnson, assumed the presidency. Lee Harvey Oswald was arrested for the assassination, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone, but conspiracy theories about the assassination persist. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act of 1964 and the Revenue Act of 1964. Kennedy ranks highly in polls of U.S. presidents with historians and the general public. His personal life has been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs. Kennedy is the most recent U.S. president to have died in office.

is for Karl Marx

Karl Marx (German: [kaʁl ˈmaʁks]; 5 May 1818 – 14 March 1883) was a German-born philosopher, political theorist, economist, journalist, and revolutionary socialist. He is best-known for the 1848 pamphlet The Communist Manifesto (written with Friedrich Engels), and his three-volume Das Kapital (1867–1894), a critique of classical political economy which employs his theory of historical materialism in an analysis of capitalism, in the culmination of his life's work. Marx's ideas and their subsequent development, collectively known as Marxism, have had enormous influence.

Born in Trier in the Kingdom of Prussia, Marx studied at the universities of Bonn, Berlin, and Jena, and received a doctorate in philosophy from the latter in 1841. A Young Hegelian, he was influenced by the philosophy of Georg Wilhelm Friedrich Hegel, and both critiqued and developed Hegel's ideas in works such as The German Ideology (written 1846) and the Grundrisse (written 1857–1858). While in Paris in 1844, Marx wrote his Economic and Philosophic Manuscripts and met Engels, who became his closest friend and collaborator. After moving to Brussels in 1845, they were active in the Communist League, and in 1848 they wrote The Communist Manifesto, which expresses Marx's ideas and lays out a programme for revolution. Marx was expelled from Belgium and Germany, and in 1849 moved to London, where he wrote The Eighteenth Brumaire of Louis Bonaparte (1852) and Das Kapital. 

From 1864, Marx was involved in the International Workingmen's Association (First International), in which he fought the influence of anarchists led by Mikhail Bakunin. In his Critique of the Gotha Programme (1875), Marx wrote on revolution, the state and the transition to communism. He died stateless in 1883 and was buried in Highgate Cemetery.

Marx's critiques of history, society and political economy hold that human societies develop through class conflict. In the capitalist mode of production, this manifests itself in the conflict between the ruling classes (the bourgeoisie) that control the means of production and the working classes (the proletariat) that enable these means by selling their labour power for wages. Employing his historical materialist approach, Marx predicted that capitalism produced internal tensions like previous socioeconomic systems and that these tensions would lead to its self-destruction and replacement by a new system known as the socialist mode of production. For Marx, class antagonisms under capitalism—owing in part to its instability and crisis-prone nature—would eventuate the working class's development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers. Marx actively pressed for its implementation, arguing that the working class should carry out organised proletarian revolutionary action to topple capitalism and bring about socio-economic emancipation.

Marx has been described as one of the most influential figures of the modern era, and his work has been both lauded and criticised. Marxism has exerted major influence on socialist thought and political movements, with Marxist schools of thought such as Marxism–Leninism and its offshoots becoming the guiding ideologies of revolutions that took power in many countries during the 20th century, forming communist states. Marx's work in economics has had a strong influence on modern heterodox theories of labour and capital, and he is often cited as one of the principal architects of modern sociology.

is for Louis XVl

Louis XVI (Louis-Auguste; French: [lwi sɛːz]; 23 August 1754 – 21 January 1793) was the last king of France before the fall of the monarchy during the French Revolution. The son of Louis, Dauphin of France (son and heir-apparent of King Louis XV), and Maria Josepha of Saxony, Louis became the new Dauphin when his father died in 1765. In 1770, he married Marie Antoinette. He became King of France and Navarre on his grandfather's death on 10 May 1774, and reigned until the abolition of the monarchy on 21 September 1792. From 1791 onwards, he used the style of king of the French.

The first part of Louis XVI's reign was marked by attempts to reform the French government in accordance with Enlightenment ideas. These included efforts to increase tolerance toward non-Catholics as well as abolishing the death penalty for deserters. The French nobility reacted to the proposed reforms with hostility, and successfully opposed their implementation. Louis implemented deregulation of the grain market, advocated by his economic liberal minister Turgot, but it resulted in an increase in bread prices. In periods of bad harvests, it led to food scarcity which, during a particularly bad harvest in 1775, prompted the masses to revolt. From 1776, Louis XVI actively supported the North American colonists, who were seeking their independence from Great Britain, which was realised in the Treaty of Paris (1783). The ensuing debt and financial crisis contributed to the unpopularity of the ancien régime. This led to the convening of the Estates General of 1789. 

 Discontent among the members of France's middle and lower classes resulted in strengthened opposition to the French aristocracy and to the absolute monarchy, of which Louis XVI and his wife, Marie Antoinette, were representatives. Increasing tensions and violence were marked by events such as the storming of the Bastille, during which riots in Paris forced Louis to definitively recognize the legislative authority of the National Assembly.

Louis's indecisiveness and conservatism led some elements of the people of France to view him as a symbol of the perceived tyranny of the ancien régime, and his popularity deteriorated progressively. His unsuccessful flight to Varennes in June 1791, four months before the constitutional monarchy was declared, seemed to justify the rumors that the king tied his hopes of political salvation to the prospects of foreign intervention. His credibility was deeply undermined, and the abolition of the monarchy and the establishment of a republic became an ever-increasing possibility. The growth of anti-clericalism among revolutionaries resulted in the abolition of the dîme (religious land tax) and several government policies aimed at the dechristianization of France.

In a context of civil and international war, Louis XVI was suspended and arrested at the time of the Insurrection of 10 August 1792. One month later, the monarchy was abolished and the French First Republic was proclaimed on 21 September 1792. The former king became a desacralized French citizen, addressed as Citoyen Louis Capet (Citizen Louis Capet) in reference to his ancestor Hugh Capet. Louis was tried by the National Convention (self-instituted as a tribunal for the occasion), found guilty of high treason and executed by guillotine on 21 January 1793. Louis XVI's death brought an end to more than a thousand years of continuous French monarchy. Both of his sons died in childhood, before the Bourbon Restoration; his only child to reach adulthood, Marie Thérèse, was given over to her Austrian relatives in exchange for French prisoners of war, eventually dying childless in 1851.

is for Maximilien Robespierre

Maximilien François Marie Isidore de Robespierre (/ˈroʊbzpjɛər/; French: [maksimiljɛ̃ ʁɔbɛspjɛʁ]; 6 May 1758 – 28 July 1794) was a French lawyer and statesman, widely recognised as one of the most influential and controversial figures of the French Revolution. Robespierre fervently campaigned for the voting rights of all men and their unimpeded admission to the National Guard. Additionally, he advocated the right to petition, the right to bear arms in self-defence, and the abolition of the Atlantic slave trade.

A radical Jacobin leader, Robespierre was elected as a deputy to the National Convention in September 1792, and in July 1793, he was appointed a member of the Committee of Public Safety. Robespierre faced growing disillusionment due in part to the politically motivated violence associated with him. Increasingly, members of the Convention turned against him, and accusations came to a head on 9 Thermidor. Robespierre was arrested and along with around 90 individuals, he was executed without trial.

A figure deeply divisive during his lifetime, Robespierre's views and policies continue to evoke controversy. His legacy has been heavily influenced by his actual or perceived participation in repression of the Revolution's opponents, but he is notable for his progressive views for the time. Academic and popular discourse continues to engage in debates surrounding his legacy and reputation, particularly his ideas of virtue in regards to the revolution and its violence.

is for Nelson Maldena

Nelson Rolihlahla Mandela (/mænˈdɛlə/ man-DEL-ə, Xhosa: [xolíɬaɬa mandɛ̂ːla]; born Rolihlahla Mandela; 18 July 1918 – 5 December 2013) was a South African anti-apartheid activist and politician who served as the first president of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election. His government focused on dismantling the legacy of apartheid by fostering racial reconciliation. Ideologically an African nationalist and socialist, he served as the president of the African National Congress (ANC) party from 1991 to 1997.

A Xhosa, Mandela was born into the Thembu royal family in Mvezo, South Africa. He studied law at the University of Fort Hare and the University of Witwatersrand before working as a lawyer in Johannesburg. There he became involved in anti-colonial and African nationalist politics, joining the ANC in 1943 and co-founding its Youth League in 1944. After the National Party's white-only government established apartheid, a system of racial segregation that privileged whites, Mandela and the ANC committed themselves to its overthrow. He was appointed president of the ANC's Transvaal branch, rising to prominence for his involvement in the 1952 Defiance Campaign and the 1955 Congress of the People. He was repeatedly arrested for seditious activities and was unsuccessfully prosecuted in the 1956 Treason Trial. Influenced by Marxism, he secretly joined the banned South African Communist Party (SACP). 

 Although initially committed to non-violent protest, in association with the SACP he co-founded the militant uMkhonto we Sizwe in 1961 that led a sabotage campaign against the apartheid government. He was arrested and imprisoned in 1962, and, following the Rivonia Trial, was sentenced to life imprisonment for conspiring to overthrow the state.

Mandela served 27 years in prison, split between Robben Island, Pollsmoor Prison, and Victor Verster Prison. Amid growing domestic and international pressure and fears of racial civil war, President F. W. de Klerk released him in 1990. Mandela and de Klerk led efforts to negotiate an end to apartheid, which resulted in the 1994 multiracial general election in which Mandela led the ANC to victory and became president. Leading a broad coalition government which promulgated a new constitution, Mandela emphasised reconciliation between the country's racial groups and created the Truth and Reconciliation Commission to investigate past human rights abuses. Economically, his administration retained its predecessor's liberal framework despite his own socialist beliefs, also introducing measures to encourage land reform, combat poverty and expand healthcare services. Internationally, Mandela acted as mediator in the Pan Am Flight 103 bombing trial and served as secretary-general of the Non-Aligned Movement from 1998 to 1999. He declined a second presidential term and was succeeded by his deputy, Thabo Mbeki. 

 Mandela became an elder statesman and focused on combating poverty and HIV/AIDS through the charitable Nelson Mandela Foundation.

Mandela was a controversial figure for much of his life. Although critics on the right denounced him as a communist terrorist and those on the far left deemed him too eager to negotiate and reconcile with apartheid's supporters, he gained international acclaim for his activism. Globally regarded as an icon of democracy and social justice, he received more than 250 honours, including the Nobel Peace Prize. He is held in deep respect within South Africa, where he is often referred to by his Thembu clan name, Madiba, and described as the "Father of the Nation".

is for Omar Torrijos

Omar Efraín Torrijos Herrera (February 13, 1929 – July 31, 1981) was the Panamanian military leader of Panama, as well as the Commander of the Panamanian National Guard from 1968 to his death in 1981. Torrijos was never officially the president of Panama, but instead held self-imposed and all-encompassing titles including "Maximum Leader of the Panamanian Revolution". Torrijos took power in a coup d'état and instituted a number of social reforms.

Torrijos is best known for negotiating the 1977 Torrijos–Carter Treaties that eventually gave Panama full sovereignty over the Panama Canal. The two treaties guaranteed that Panama would gain control of the Panama Canal after 1999, ending the control of the canal that the U.S. had exercised since 1903. On December 31, 1999, the final phase of the treaty, the US relinquished control of the Panama Canal and all areas in what had been the Panama Canal Zone.

His son Martín Torrijos was president from 2004 to 2009.

is for Philip ll

Philip II (21 May 1527 – 13 September 1598), sometimes known in Spain as Philip the Prudent (Spanish: Felipe el Prudente), was King of Spain from 1556, King of Portugal from 1580, and King of Naples and Sicily from 1554 until his death in 1598. He was also jure uxoris King of England and Ireland from his marriage to Queen Mary I in 1554 until her death in 1558. Further, he was Duke of Milan from 1540. From 1555, he was Lord of the Seventeen Provinces of the Netherlands.

The son of Emperor Charles V and Isabella of Portugal, Philip inherited his father's Spanish Empire in 1556, and succeeded to the Portuguese throne in 1580 following a dynastic crisis. The Spanish conquests of the Inca Empire and of the Philippines, named in his honor by Ruy López de Villalobos, were completed during his reign. Under Philip II, Spain reached the height of its influence and power, sometimes called the Spanish Golden Age, and ruled territories in every continent then known to Europeans. Philip led a highly debt-leveraged regime, seeing state defaults in 1557, 1560, 1569, 1575, and 1596. 

 This policy was partly the cause of the declaration of independence that created the Dutch Republic in 1581. Philip finished building the royal palace El Escorial in 1584.

Deeply devout, Philip saw himself as the defender of Catholic Europe against the Ottoman Empire and the Protestant Reformation. In 1584, Philip signed the Treaty of Joinville, funding the French Catholic League over the following decade in its civil war against the French Huguenots.

 In 1588, he sent an armada to invade Protestant England, with the strategic aim of overthrowing Elizabeth I and re-establishing Catholicism there, but his fleet was defeated in a skirmish at Gravelines (northern France) and then destroyed by storms as it circled the British Isles to return to Spain. The following year Philip's naval power was able to recover after the failed invasion of the English Armada into Spain. Two more Spanish armadas unsuccessfully tried to invade England in 1596 and 1597. The Anglo-Spanish War carried on until 1604, six years after Philip's death.

is for Queen Elizabeth l

Elizabeth I (7 September 1533 – 24 March 1603) was Queen of England and Ireland from 17 November 1558 until her death in 1603. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

Elizabeth was the only surviving child of Henry VIII and his second wife, Anne Boleyn. When Elizabeth was two years old, her parents' marriage was annulled, her mother was executed, and Elizabeth was declared illegitimate. Henry restored her to the line of succession when she was 10, via the Third Succession Act 1543. After Henry's death in 1547, Elizabeth's younger half-brother Edward VI ruled until his own death in 1553, bequeathing the crown to a Protestant cousin, Lady Jane Grey, and ignoring the claims of his two half-sisters, the Catholic Mary and the younger Elizabeth, in spite of statutes to the contrary. Edward's will was set aside within weeks of his death and Mary became queen, deposing and executing Jane. During Mary's reign, Elizabeth was imprisoned for nearly a year on suspicion of supporting Protestant rebels.

Upon her half-sister's death in 1558, Elizabeth succeeded to the throne and set out to rule by good counsel. She depended heavily on a group of trusted advisers led by William Cecil, whom she created Baron Burghley. One of her first actions as queen was the establishment of an English Protestant church, of which she became the supreme governor. This arrangement, later named the Elizabethan Religious Settlement, would evolve into the Church of England. It was expected that Elizabeth would marry and produce an heir; however, despite numerous courtships, she never did. Because of this she is sometimes referred to as the "Virgin Queen". She was eventually succeeded by her first cousin twice removed, James VI of Scotland.

In government, Elizabeth was more moderate than her father and siblings had been. One of her mottoes was video et taceo ("I see and keep silent"). In religion, she was relatively tolerant and avoided systematic persecution. After the pope declared her illegitimate in 1570, which in theory released English Catholics from allegiance to her, several conspiracies threatened her life, all of which were defeated with the help of her ministers' secret service, run by Sir Francis Walsingham. Elizabeth was cautious in foreign affairs, manoeuvring between the major powers of France and Spain. 

 She half-heartedly supported a number of ineffective, poorly resourced military campaigns in the Netherlands, France, and Ireland. By the mid-1580s, England could no longer avoid war with Spain.

As she grew older, Elizabeth became celebrated for her virginity. A cult of personality grew around her which was celebrated in the portraits, pageants, and literature of the day. The Elizabethan era is famous for the flourishing of English drama, led by playwrights such as William Shakespeare and Christopher Marlowe, the prowess of English maritime adventurers, such as Francis Drake and Walter Raleigh, and for the defeat of the Spanish Armada. Some historians depict Elizabeth as a short-tempered, sometimes indecisive ruler, who enjoyed more than her fair share of luck. Towards the end of her reign, a series of economic and military problems weakened her popularity. Elizabeth is acknowledged as a charismatic performer ("Gloriana") and a dogged survivor ("Good Queen Bess") in an era when government was ramshackle and limited, and when monarchs in neighbouring countries faced internal problems that jeopardised their thrones. After the short, disastrous reigns of her half-siblings, her 44 years on the throne provided welcome stability for the kingdom and helped to forge a sense of national identity.
