Stephen William Hawking was born on January 8,1942(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 about 20 miles north of London.At eleven Stephen went to St All.School，and then on to University College，Oxford，his father's old college.Stephen wanted to do mathematics，although his father would have preferred medicine.Mathematics was not available at University College，so he did physics instead.
Stephen then went on to Cambridge to do research in cosmology(宇宙论)．After gaining his PHD，he became first a research fellow，and later on a professional fellow at Gonville & Caius College.After leaving the Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics and Theoretical Physics，and since 1979 has held the post of Lucasian Professor of Mathematics.The chair was founded in 1663 with money left in the will of the Reverend Henryucas，who had been the Member of Parliament for the University.It was first held by Isaac Barrow，and then in 1669 by Isaac Newton.
His many publications include The Large Scale Structure of Spacetime with G．F.R.Ellis，General Relativity：An Einstein Centenary Survey with W．Israel，and 300 Years of Gravity with W．Israel.Stephen Hawking had two popular books published：his best seller A Brief History of Time，and his later book，Black Holes and Baby Universes and other essays.
