Hawking was born on January 8, 1942 in Oxford, England. He spent most of his childhood in and around London, and always looked to learn. He loved the stars and space. Stephen Hawking wanted to study mathematics and physics in a university, but his father thought that there would not be any jobs in mathematics, so Hawking took physics and chemistry, and only a bit of math. No one really saw how intelligent Hawking was till the second year of college.
One ordinary day at college, Hawking fell down a flight of stairs. He had forgotten who he was for two hours. When he back to himself, he took a Mensa test and got a 250. He thought nothing of the fall and went on like he normally would. When Hawking graduated college he took a trip to Persia. He got very ill on this trip, and was later diagnosed Amtytropic lateral sclerosis or, Lou Gerhig's disease.
When the doctors diagnosed with 2 1/2 years to live he pretty much gave up. He stopped researching and experimenting, and even thought of not finishing his Ph.D. He was in a hard depression, until he met a women by the name of Jane Wilde. After finishing his thesis, Jane Wilde and Stephen Hawking were married.
From then on, Hawking went on to bigger things. The doctors diagnosis was wrong, Hawking wouldn't die in the 2 1/2 year. Hawking is credited with many things having to do with Black Holes and the outer space. Even know Hawking's problems did not kill him, they did not get any better. Years after the diagnosis Hawking eventually has become restricted to a wheelchair and can hardly move. He talks through a voice synthesizer and is fed through intervenes.
Despite all the complications, Hawking continues to research and has not forgotten his goal -- to find some type of grand unification theorem, however...
