Stephen William Hawking was an english theoretical physicist and cosmologist. He was quite notorious for his discovery of black hole theorem. 

Hawking was born on January 8th, 1942 in Oxford into a family of physicians, Frank and Isobel Eileen Hawking. Hawking had two younger sisters, Philippa and Mary, and an adopted brother, Edward Frank David. 

Hawking began his schooling at the Byron House School in Highgate, London. Although known at school as "Einstein", Hawking was not initially successful academically. He slowly started to show considerable aptitude for scientific subjects and decided to read mathematics at university. 

He then began his university education at University College, Oxford in October 1959.

In 1963, Hawking was diagnosed with motor neuron disease, or usually known as Amyotrophic lateral sclerosis (ALS). When Hawking first found out, he fell into depression. In the last years of his life, he was a man with an extremely weak body, unable to move about without a wheelchair, or even to speak without a machine.
