Stephen Hawking !

                        

Stephen William Hawking, is an English theoretical physicist and cosmologist, whose scientific career spans over forty years. His books and public appearances have made him an academic celebrity. 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 a motor neurone disease known as amyotrophic lateral sclerosis(ALS).
 Hawking's illness is markedly different from typical ALS in that his form of ALS would make for the most protracted case ever documented. A survival for more than ten years after diagnosis is uncommon for ALS; the longest documented durations are thirty-two and thirty-nine years and these cases were termed benign because of the lack of the typical progressive course.
