Stephen Hawking is one of the most remarkable figures of our time, a Cambridge genius who has earned international celebrity as a brilliant theoretical physicist and become an inspiration and revelation to those who have witnessed his courageous triumph over disability. This is Hawking's life story by Kitty Ferguson, who has had special help from Hawking himself and his close associates and who has a gift for translating the language of theoretical physics for non-scientists.

Twenty years ago, Kitty Ferguson's Stephen Hawking: Quest for a Theory of Everything became a Sunday Times bestseller and took the world by storm. She now returns to the subject to transform that short book into a hugely expanded, carefully researched, up-to-the-minute biography.
