The trolley used by physicist Stephen Havking sold nearly 300,000 pounds ($ 393,000) at the auction, while a copy of the doctoral thesis got nearly 585,000 pounds ($ 767,000), Christie's auctioneer said on Thursday.
The motorized chair, used by Hawking after paralysis with motor neuronal diseases, increased 296,750 pounds ($ 385,122) at Christie's online auction. It was expected to reach 15,000 pounds ($ 19,467).
Revenue from the sale of the chair will be in two charities, the Foundation Stephen Havking and the Association of Motor Neurons.
Hawking's thesis of the University of Cambridge, 1965, "Real Estate Expansion Universities" sold for 584,750 pounds ($ 758,888), more than three times the estimated pre-sales price, at an online auction.
Diagnosed with motor neuron diseases at 22 and with only a few years of age, Huking died in March 76 instead of 76. He expanded his scientific thinking about the black holes and the origin of the universe and achieved the status of fame, wrote best-selling books and a visiting actor at "Simpsons".
The script of one of his appearances on an animated TV show sold for £ 6,250 ($ 8,111) in the sale of 22 Havking items, while a collection of his medals and prizes increased $ 296,750 ($ 385,122).
Hawking's daughter Lucy said that the sale gave "fans of her work a chance to get a memorial to the extraordinary life of our father in the form of a small selection of evocative and fascinating things."
Hawking's children hope to preserve a scientific archive for the nation. Christie led the negotiations to hand it over to the British authorities instead of the inheritance tax.
