Hawking’s thesis, wheelchair sell for $1m

A motorised wheelchair used by the late British physicist Stephen Hawking sold at auction on Thursday for almost £300,000 ($391,740.00) while a dissertation raised nearly twice that at a sale to raise money for charity.

Famed for his work exploring the origins of the universe, Hawking died in March at the age of 76 after spending most of his life confined to a wheelchair with motor neurone disease. Some of his belongings including essays, medals, awards and a copy of his book a "Brief History of Time" signed with a thumbprint were sold online on Thursday alongside letters and manuscripts belonging to Isaac Newton, Charles Darwin and Albert Einstein.

Hawking's 117-page dissertation "Properties of expanding universes" from 1965 sold for £584,750, well ahead of the estimate of up to 150,000. Medals and awards sold for £296,750, compared with an estimate of £15,000, while the red motorised wheelchair sold for £296,750, also compared with an estimate of £15,000.
