'This is without doubt the definitive biography of Hawking, the uniquely brilliant theoretical physicist and the global superstar. With unprecedented access to archives, letters, and diaries, newly unearthed family details, and deep insights into Hawking's work, Farmelo has cemented his reputation as the very best science biographer of his generation.'

'When one is faced with the possibility of early death, it makes one realise that life is worth living.' Stephen Hawking

An insatiable curiosity and appreciation for life powered Stephen Hawking to the furthest reaches of the universe and human achievement: during his remarkable lifetime he shed light on many of the mysteries of black holes and made key contributions to our understanding of the beginnings of the universe, all while captivating the world and selling more than 25 million copies of A Brief History of Time.

A brilliant theoretical physicist, Hawking lived one of the most extraordinary lives of the past century. And yet, none of this should have been possible. Aged 21, he was given only a few years to live - and spent the next fifty-five showing what can be achieved despite near-hopeless odds.

Drawing on his parents' previously unseen letters and diaries, and exclusive interviews with Stephen's family, friends and closest colleagues, Costa Award-winning biographer and physicist Graham Farmelo reveals the complex man behind the theories and global celebrity - and the resilience, fortitude and support that enabled him to defy his life-limiting diagnosis.

Vividly told and rigorously researched, Hawking is the definitive portrait of an exceptional man and extraordinary intellect.
