A Brief History of Stephen William Hawking

Stephen William Hawking was born on January 8, 1942 (Exactly 300 years after the death of Galileo) in Oxford, England. His parents ‘house was in north London, but during the Second World War Oxford was considered a safer place to have babies. When he was eight, his family moved to St Albans, a town located about 20 km north of London. At eleven Stephen went to St Albans School, then at University College, Oxford, his father l ‘former college. Stephen wanted to do mathematics, although his father would have preferred medicine. Mathematics was not available at University College, he is rather physical. After three years and not much work he received a first class honors degree in natural sciences.



Stephen then went to Cambridge to do research in cosmology, in the absence of a work in this area in Oxford at the time. His supervisor was Denis Sciama, although he had hoped to get Fred Hoyle who was working in Cambridge. After earning his doctorate he became the first researcher, and later on a Professorial Fellow at Gonville and Caius College. After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics since 1979 and has held the post of Lucasian Professor of Mathematics. The President was founded in 1663 with money left in the will of Reverend Henry Lucas, who was a member of the University. It was first held by Isaac Barrow, then in 1663 by Isaac Newton.

Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose, he showed that Einstein ’s General Theory of Relativity implied space and time have a beginning in the Big Bang and an end in black holes. These results indicated that it was necessary to unify general relativity with quantum theory, the other great scientific development of the first half of the 20th century. One consequence of such a unification it was discovered that black holes should not be completely black but emit radiation and eventually evaporate and disappear. Another conjecture is that the universe has no edge or boundary in imaginary time. This would imply that how the universe began was completely determined by the laws of science.

His numerous publications include The Large Scale Structure of Spacetime with GFR Ellis, general relativity: Einstein Centenary Survey, with W Israel, and 300 years of gravity, with W Israel. Stephen Hawking has published two books, his best-selling A Brief History of Time, and his book later, black holes and baby universe and other tests. Professor Hawking has twelve honorary doctorates, received the CBE in 1982 and made a Companion of Honour in 1989. He is the recipient of many awards, medals and prizes and is a Fellow of the Royal Society and a member of the U.S. National Academy of Sciences. Stephen Hawking continues to combine family life (he has three children and one grandchild), and his research in theoretical physics together with an extensive programme of travel and public lectures.
