Proceedings of the auction raised by wheelchair will go to the Stephen Hawking Foundation that assists research into cosmology and astrophysics, and to the Motor Neurone Disease Association that supports research and campaigns for those diagnosed with the disease. A motorised wheelchair that belonged to the physicist, who died in March and which was expected to fetch £15,000, went for nearly £300,000.
"Stephen Hawking was a huge personality worldwide", Thomas Venning, head of the Books and Manuscripts department at auction house Christie's London, told Reuters prior to the auction.
A bidder also spent more than US$760,000 - more than double the expectation - on Prof Hawking's signed 1965 PhD thesis, Properties of Expanding Universes, about the origins of time and space.
Recently in great Britain was sold to the wheelchair world-famous scientist Stephen Hawking.
An invitation he sent out to a party held several years previously, a light-hearted experiment to see if any time travellers would turn up, sold for more than 10 times its pre-sale estimate of £100, while a bomber jacket he wore in a 2016 documentary raised £40,000.
A total of 22 items were sold during the online auction.

Hawking died at the age of 76 in March, he suffered from motor neuron disease most of his life. All of those were sold, and the total, about US$1.8 million, was seven times more than had been predicted.
The second-highest price of Hawking's collection was achieved by a selection of medals and awards presented throughout his career, which sold for £296,750 ($388,970).
Altogether, the items auctioned, which also included possessions of Isaac Newton, Charles Darwin and Albert Einstein, were sold for more than US$2.3 million.
Sophie Hopkins, specialist in manuscripts and archives at Christie's, said much of the collection was "incredibly iconic".
