Stephen Hawking, the greatest scientist after Einstein, was born in England in 1942. In his book ‘A Brief History of Time: From the Big Bang to Black Holes’ (1988), he explained cosmology, and thus, established his reputation as a great scientist.
In 1968, he received his PhD in cosmology from Cambridge University. But unfortunately, he became a victim of Gehrig’s disease in 1972 and was confined to a wheel chair.
Yet, he continued his research and won Albert Einstein award in 1974 for theoretical physics. He had been a Lucasian Professor of Mathematics in Cambridge University since 1979.
