Hawking was a renowned scientist, cosmologist, astronomer, and mathematician. He authored several books, including his best-selling 1988 classic A Brief History of Time, which has sold more than 10 million copies.

Hawking was diagnosed with the degenerative disease amyotrophic lateral sclerosis, also known as Lou Gehrig's disease, at the age of 21. He was given just a few years to live, but battled the illness for more than five decades.
