The car seat for the famous British physicist Steven Hawking was auctioned at £ 296,500 (€ 341,191), but his doctoral thesis was almost double, announced auction house Christie on Thursday.
The seat sold was "the earliest preserved example" for the chairs that Hawking told Christie after becoming paralyzed for the diagnosed motor neuron disease.
Hawking used this chair from the late eighties to the mid-nineties until he could not handle this chair by hand.
The wheelchair was sold as a collection item, not for medical use. The revenue from its sale will be donated to two charitable foundations – the Stevens Hawking Foundation and the Motoro-Neuronal Association.
Hawking's 1965 original PhD thesis from the University of Cambridge was sold for $ 767,000 (€ 675,500) in the same auction at the same time. Other items, including the blouse, were auctioned for a total of $ 650,000 (€ 572,450).
At the auction, including Aizek Newton, Charles Darwin and Albert Einstein, 52 articles were sold. Their total price has exceeded 2.3 million dollars (two million euros).
Houghton, at the age of 21, was diagnosed with motor neuron disease in amyotrophic lateral sclerosis, which allowed him to travel only with a wheelchair and subsequently lost his ability to speak. Despite severe disease, Hawking has been actively involved in scientific and social life. He died on March 14 this year at the age of 76 at his Cambridge residence.
