Stephen Hawkinng - A world renowned Scientist,Physicist & Writer

Disability: Motor Neuron disease or a variant of ALS (Amyotrophic Lateral Sclerosis)

Stephen William Hawking is a British theoretical physicist, whose world-renowned scientific career spans over 40 years. His books and public appearances have made him an academic celebrity and he is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.

Stephen Hawking is severely disabled by motor neuron disease, likely a variant of the disease known as amyotrophic lateral sclerosis (or ALS). Symptoms of the disorder first appeared while he was enrolled at Cambridge; he lost his balance and fell down a flight of stairs, hitting his head. Worried that he would lose his genius, he took the Mensa test to verify that his intellectual abilities were intact. The diagnosis of motor neuron disease came when Hawking was 21, shortly before his first marriage, and doctors said he would not survive more than two or three years. Hawking gradually lost the use of his arms, legs, and voice, and as of 2009 was almost completely paralyzed.
