"This book looks at the ... life of Stephen Hawking, the brilliant scientist who was diagnosed with Lou Gehrig's disease (ALS) at the age of 21 and told that he had two years to live, but 50 years later is still working and helping to popularize science. The book describes his early life and studies in college, his scientific discoveries, and how he has coped with his disability. It also looks at how his work is being continued by other scientists."--Back cover.
