A wheelchair by physicist Stephen Hawking was sold for nearly 300,000 pounds ($ 393,000) at auction, while a copy of his thesis yielded nearly £ 585,000 ($ 767,000), said auctioneer Christie's on Thursday.
Hawking's motorized stool, paralyzed by motor neurone disease, raised 296,750 pounds in a Christie online auction. It was expected to lift up to 15,000 pounds.
Proceeds from the sale of the chair will benefit two charities, the Stephen Hawking Foundation and the Motor Neurone Disease Association.
Hawking's 1965 University of Cambridge dissertation, "Properties of the Expanding Universes," sold for 584,750 pounds in the online auction, more than three times his pre-sale estimate.
Hawking was diagnosed with motor neurons at the age of 22 and received only a few years to live. Instead, Hawking died in March at 76 years, expanding scientific thinking about black holes and the origins of the universe and attaining fame by writing bestselling books and guesting on The Simpsons (19659005). A screenplay from one of his appearances in the animated television series sold for £ 6,250 selling 22 Hawking items, while a collection of his medals and awards earned £ 296,750.
Hawkings daughter Lucy said the sale gives "admirers of his work the chance to earn a souvenir of our father's exceptional being his life in the form of a small selection of evocative and fascinating objects."
Hawking's children hope to be scientific To get archive for the nation. Christie's is negotiating the transfer to the UK authorities instead of inheritance tax.
