The engine chair for the famous English physicist Steven Hawking was auctioned at £ 296,500 (€ 341,191), but his doctoral dissertation was almost doubled, as Christie auctioneer said on Thursday.
The chairs were "the oldest preserved example" for chairs that Hawking once called Christie when it became a paralyzed diagnosed motor neuron disease.
Hawking used this chair from the late 1980s until the mid-1990s until he was able to handle this chair manually.
The wheelchair was sold as a collector's item, not for medical use. Revenue from its sale will be donated to two charities – the Stevens Hawking Foundation and the Motoro Neuron Association.
Hawking's original doctoral work from 1965 at Cambridge University was sold at $ 767,000 (€ 675,500) at the same auction at the same time. Other items, including a blouse, were auctioned a total of $ 650,000 (€ 572,450).
At auction, which included Aizka Newton, Charles Darwin and Albert Einstein, 52 items were sold. Their total cost exceeded $ 2.3 million (two million euros).
Houghton, at the age of 21, was diagnosed with motor neuron disease in amyotrophic lateral sclerosis, which allowed him to move only with a wheelchair and later lost his ability to speak. In spite of serious illness, Hawking actively participated in scientific and social life. He died on March 14 this year at the age of 76 at his home in Cambridge.
