In the 1980s and 1990s, the theoretical physicist Stephen Hawking's wheelchair exceeded sales expectations at online auctions held on Thursday.
The value of the chair was estimated at up to $ 19,500 (£ 15,000) early, but eventually sold at $ 387,480 (£ 296,750). CNN Reported. This amount is 20 times more than anticipated sales.
It was also sold more than the manuscripts of other well-known scientists.
Hawking used wheelchairs after being paralyzed by amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease, a neurodegenerative disease.
"Hawking initially resisted the idea of wheelchair use in the late 1960s, until the late 1970s, he was using a motorized model like the current example, and even famous for being a wild driver," said Christie Auctioneer said.
"By the late 1980s he had gained a reputation and was logically the most traveled metaphorically, literally, given the range of intellectual expeditions to space and time, as well as the extensive trips to meetings and public events."
The proceeds from the sale of the chair are sent to two charitable organizations, the Motor Neuron Disease Association and the Stepking Hawking Foundation.
"On the shoulders of the giant" sales include a copy of the Hawking Medal and Award, and Dr. Hawking. proposition.
The paper was expected to sell for up to $ 195,800 (£ 150,000) to secure it, while buyers would sell for $ 763,300 (£ 584,750).
Hawking's work has brought more than Isaac Newton, Charles Darwin, and Albert Einstein's work. Darwin's letter was sold for $ 64,700 (£ 50,000) and Newton's manuscript was sold for $ 129,400 (£ 100,000). A bidder also agreed to pay $ 42,054 (£ 32,500) for one of Einstein's manuscripts.
Hawking was 21 years old when diagnosed with ALS. He was told that he had lived only a few years to live because of his illness.
Hawking, however, lived for many more decades, during which he expanded scientific thinking about black holes and universe. He taught lectures and wrote books, of which 1988 A brief history of time, Has become one of the best-selling science books of all time.
Hawking died at his home in Cambridge on March 14. He was 76 years old.
Hawking's daughter, Lucy, said the sale gave her father's followers an opportunity to get a keepsake of a scientist's special life.
