Sell a wheelchair used by Sitvin Hawking for about 300,000 pounds ($ 393,000), while a copy of the doctoral thesis of the late physicist sold for 585 thousand pounds ($ 767 thousand) in an online auction in London.
The wheelchair, which Hawking used after being paralyzed by motor neuron disease, was auctioned to Christie's on a record after he was expected to sell for between £ 10,000 and £ 15,000.
The sale of the chair is intended for the Stephen Hawking Foundation and the Society of Motor Neuroscience.
A copy of Hawking's doctoral thesis, prepared in 1965 on the origin of the universe, was sold for £ 58,450, three times higher than pre-sale estimates, in the auction that ended Thursday.
Hawking died in March of 76 years after doctors said he would only live for a few years after being diagnosed with motor neuron when he was 22.
