Stephen Havking stroller and a set of his medals and awards were sold for a total of about 600,000 pounds, while a copy of the Doctor's documents increased almost that amount independently on auction items belonging to him and other famous scientists.
The sale, launched by Christie's online and included 52 lots, increased more than 1.8 million pounds on Thursday. They included items belonging to Hawking, as well as others associated with Isaac Newton, Charles Darwin and Albert Einstein.
It is expected that the dissertation will sell up to 150,000 pounds, but the buyer will ultimately offer 584,750 pounds for insurance. The motorized wheelchair Hawking was sold for £ 296,750, as well as seven prizes, including the Albert Einstein Prize for Natural Science. One of Newton's manuscripts was sold for 100,000 pounds, Darwin's letter went 50,000 pounds, and the bidders agreed to pay 32,500 pounds for one of Einstein's manuscripts.
The sale is called "On the shoulders of the giant" – a reference to the famous phrase Newton once used from his own achievements: "If I see it further, it stands on the shoulder of the Giants."
Money raised by selling wheelchairs will go to the Foundation Stephen Havking and the Association of Motor Neurons. Hoking survived motor neuron diseases for most of his life, before he died at the age of 76 in March.
Also sold are personal copies of British physicist documents, such as a copy of his 1974 Black Hole Eplosions?, In which he predicted that black holes would release airborne radiation, known as Havking Radiation. Paper is sold for 7500 pounds.
A copy of his bestseller A short history of time, signed with a fingerprint, sold for 68,750 pounds, a bomber jacket lasted 40,000 pounds, and the script for one of his performances at The Simpsons sold for £ 6,250.
Hawking's daughter Luci 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 items."
Hawking's children hope to preserve a scientific archive for the nation. Christie led negotiations to hand over them to the British authorities instead of inheritance tax.
Other significant items included a document that Isaac Newton signed to repay a loan, sold for 56,250 pounds, a letter from Charles Darwin described as his "great review of naturalist's report on Challenger expedition, "which was sold for £ 15,000 and a copy of Einstein's views on Newton, formerly owned by his former son and sold for £ 13,750.
