The motorcycle wheelchair used by British physicist Stephen Hawking was auctioned on Thursday at almost 300,000 kilograms (391,700 crowns), while the doctoral dissertation almost double the sale to raise money for charity.
Hawking died of being known to study the origin of the universe and died in March 76 at the age of 76 after spending most of his life on a wheelchair due to a motor neurone attack.
Some of his possessions including essays, medals, awards, and a copy of his book, "Short History of Time", signed on a thumbnail, were sold on Thursday with Isaac Newton, Charles Darwin and Albert Einstein's Letters and Manuscripts.
Hawking's 117-page doctoral dissertation "Features of Expanding Universes" for 1965 sold 584,750 pounds, which is far more than 150,000 estimates.
Medals and prizes were sold 296,750 pounds, estimated at 15,000 pounds, while the red motorized wheelchair was sold 296,750 pounds, compared to 15,000 pounds.
Auction House Christies spent nine days with online auction called "Giants on the shoulders" to raise money for the Stephen Hawking Foundation and the Motor Neurone Disease Association.
It also offered fans of the known physicist to an electronic sound synthesizer the opportunity to buy some of their possessions.
"Stephen Hawking was a huge personality in the world, and he had this amazing ability to communicate with people," Thomas Venning, director of the Christie's London Book and Manuscript Director at the auction house told Reuters before the event.
