On March 14, 2018, the world said goodbye to one of science’s great popularizers. Stephen Hawking was as renowned for his theories on time and space as he was for his unique life story. Undeterred by his debilitating illness, he trained his mind to work in a new way, visualizing problems rather than writing equations, and turning into the leading light in modern science. This fully illustrated biography follows him from an unremarkable upbringing in St. Albans to his success as the most celebrated and inspiring scientist of his generation, taking in his family life and scientific breakthroughs. It offers a historical perspective on his achievements, and reveals how he turned a degenerative condition into his calling card and, perhaps, the source of his greatest triumphs.
