In 1963 Stephen Hawking was given two years to live. Defying all the odds, he died in March 2018 at age seventy-six as the most celebrated scientist in the world. This carefully researched, and now newly updated, up-to-the-minute biography and tribute gives a rich picture of Hawking's remarkable life - his childhood, the heart-rending beginning of his struggle with motor neurone disease, his ever-increasing international fame, and his long personal battle for survival in pursuit of a scientific understanding of the universe. From more recent years, Kitty Ferguson describes his inspiring leadership at the London Paralympic Games, the release of the film The Theory of Everything, his continuing work on black holes and the origin of the universe, the discovery of `supertranslations', and the astounding `Starshot' program. Here also are his intense concern for the future of the Earth and his use of his celebrity to fight for environmental and humanitarian causes, and, finally, a ground-breaking paper he was working on at the time of his death, in which he took issue with some of his own earlier theories. Throughout, Ferguson summarizes and explains the cutting-edge science in which Hawking was engaged.

In March, 2018, tributes poured in from around the world and friends and strangers Hawking had inspired gathered for his funeral in Cambridge and the interment of his ashes in Westminster Abbey. Ferguson offers vivid first-hand descriptions of both these occasions and, in an amazing and revealing tribute, assesses Hawking's legacy in and out of science.
