A number of personal belongings belonging to the late Stephen Hawking, one of the most respected physicists in history, are now being auctioned at Christie's.
As of Wednesday, the online sale titled "On the Shoulders of the Giants" with 22 personal belongings by the renowned scientist is open to the public, including a copy of his 1963 doctoral degree thesis and graduation with his iconic wheelchair.
"This is a scientist who has made cosmology understandable to humans," said Sophie Hopkins, Christie's manuscript and archive specialist, to ABC News. "The same scientist who thought at the same time that the Simpsons are the best on American television."
Hawking died in March at the age of 76, fifty-five, after living only two years.
When he was 21, Hawking was diagnosed with amyotrophic lateral sclerosis (ALS), a disease that causes neurons responsible for voluntary exercise. The disease paralyzed him. The proceeds from the sale of the Hawking chair at the auction will go to the Stephen Hawking Foundation and the Motor Neurone Disease Association.
