The selling chair was the "earliest preserved example" for chairs that Hawking used after paralysis, announced Christie & apos; s.
Hawking used this chair from the late '80s until the mid-90s until he could no longer handle the chair manually.
The wheelchair was sold as a collection object, not for medical use. Revenue from its sale will be disbursed to two charities – the Stevens Hawking Foundation and the Motoro Neuron Disease Association.
In the 1966 edition of Cambridge University, Hawking's original doctoral dissertation was sold for $ 767,000 (€ 675,500) at the same Internet auction. Other items, including his blouse, were auctioned for a total of $ 650,000 (€ 572,450).
The auction, including Aizek Newton, Charles Darwin and Albert Einstein, sold 52 items. Their total price exceeded $ 2.3 million (two million euros).
Houghton, 21, was diagnosed with amyotrophic lateral sclerosis, which allowed him to move only by wheelchair, but later lost his ability to speak. Despite the serious illness, Hawking has been actively involved in scientific and social life. He died on March 14, this year, at the age of 76 at his home in Cambridge.
