A WHEELCHAIR used by physicist Stephen Hawking has sold at auction for more than $ 540 600, while a copy of his doctoral thesis was collected for more than $ 1.05 million, revealed the British auction house Christie this week.
The red leather-engineered chair was used by the physicist after he was paralyzed with motor neuronal disease and was expected to initially increase $ 26,900.
Revenue from wheelchair sales will be distributed between two charity organizations, the Stephen Hawking Foundation and the Motor Neurone Disease Association.
Prof Hawking's 1965 Cambridge University dissertation, "Expanding Universe Features", was sold for more than $ 1.05 million, more than three times more than its pre-sales estimate, in the online auction.
Diagnosed with motor neuronal disease at the age of 22 and gave only a few years to live, however, Professor Hawking was in March at the age of 76.
He expanded the scientific thinking about black holes and the universe's origins, achieved global celebrity status, wrote best-selling books and guest shows on The Simpsons.
A script from one of his performances on the animated TV series was sold at $ 11,235 for the sale of 22 Prof Hawking articles, while a collection of his medals and awards increased over $ 530,000.
His daughter, Lucy, said the sale gave "admirers of his work the chance to get a memorable one of our father's extraordinary life in the form of a small selection of moody and fascinating things."
Hawking children hope to maintain their scientific archives for the nation.
Christie's auction house handles negotiations to hand over the archives to the British authorities instead of inheritance tax.
Nine-day auction, "On The Shoulders of Giants", also sold articles belonging to other major researchers, including Isaac Newton, Charles Darwin and Albert Einstein.
