A wheelchair used by physicist Stephen Hawking has sold at auction for almost 300,000 pounds ($393,000), auctioneer Christie’s said Thursday.
The red wheelchair was used by Dr. Hawking during the late 1980s and early ’90s; he stopped using it when he could no longer steer it with his hands. The physicist spent most of his life steadily losing control over his muscles because of amyotrophic lateral sclerosis, or Lou Gehrig’s disease.
The motorized chair, used by Hawking after he was paralyzed with motor neuron disease, has sold at Christie’s online auction. It had been expected to fetch up to 15,000 pounds.
Proceeds from the chair’s sale will go to two charities, the Stephen Hawking Foundation, and the Motor Neurone Disease Association.
