A copy of Stephen Hawking's shaky hand-signed dissertation was the culmination of an auction of personal items by the British physicist in London, which raised nearly € 1.4 million (€ 1.8 million).
The copy, one of only five originals of the dissertation titled "Properties of Expanding Universes," beat presale expectations four times and sold them for 584,750 at the Christies sale, which ended on Thursday.
A red leather wheelchair that Hawking used from the late 1980s to the mid-1990s, when he was driving himself with a joystick, he sold for 296,750, while an early edition of his bestseller "A Short History of Time" with a Fingerprint was marked, which was retrieved £ 68,750.
A script of one of his appearances in the television series "The Simpsons" was one of 22 lots under the hammer sold for £ 6,250.
The collection highlighted the brilliance, determination and humor of Hawking, who died in March at the age of 76, after a lifetime spent trying to unlock the secrets of the universe.
Hawking published his doctoral thesis in 1965, two years after the diagnosis of Amyotrophic Lateral Sclerosis (ALS), a form of motor neurone disease that would eventually paralyze him.  His first wife Jane typed in the 117 pages, but added two handwritten signatures and the words "This thesis is my original work" as well as some mathematical equations in it.
When the document was made available Last year online from Cambridge University, where Hawking spent his career, it was so popular that it crashed the site.

"We are very pleased to receive Christie's support to assist us in the important matter of managing the archives of our beloved father and his uniq. A valuable collection of personal and professional things documenting his life and work," said the daughter of the physicist Lucy Hawking before the sale.
"We also give admirers of his work the chance to acquire a memory of our father an extraordinary life in the form of a small selection of evocative and fascinating objects."
An invitation he sent to a party a few years earlier was a light-hearted experiment to see if the travelers showed up and sold for more time more than 10 times the estimated price of 100 before the sale, while a bomber jacket he wore in a documentary in 2016 raised 40,000 had applied.
The articles are just a small selection from Hawking's archive, which instead donates his family to the nation to pay inheritance tax, although it is not yet known where it will be stored.
The auction money goes to the family, although the money from the sale of the wheelchair is donated to the Motor Neurone Disease Association and the Stephen Hawking Foundation.
