The late famed British physicist Stephen Hawking’s most significant posessions are to be put up for auction later this month. His script from his featuring in The Simpsons, his earliest still-around wheelchair, a copy of his PhD thesis, and a bomber jacket are all going under the hammer.

The astronomer, writer, mathematician and cosmologist died back in March aged 76. Doctors told Hawking in 1963 that he would die in his 20s from a rare form of motor neurone disease, amyotrophic lateral sclerosis. He was paralysed and only able to use a few fingers on one hand, relying on his wheelchair and communicative technology.

The online auction will go down at Christie’s in London next week. It will feature 22 pieces belonging to Hawking, with some of the money going towards the Stephen Hawking Foundation and the Motor Neurone Disease Association. One of the most sought after pieces is his 1965 PhD from Cambridge University, ‘Properties of Expanding Universes’, which is expected to fetch around £150,000. His first wheelchair is expected to go for between £10,000 and £15,000.

“We are giving admirers of his work the chance to acquire a memento of our father’s extraordinary life in the shape of a small selection of evocative and fascinating items,” Hawking’s daughter Lucy said.

A statement from Christies said of the wheelchair up for auction: “By the late 1980s he was at the height of his fame, and given his extensive travels to conferences and public events, as well as the scope of his intellectual explorations of space-time, this is arguably both literally and metaphorically the most-traveled wheelchair in history.” 

And on his Simpsons TV series script, in which he appeared on September 26 2010: “Stephen Hawking made four appearances in The Simpsons over a period of 10 years, something he joked made him more famous than anything he had done in science. A small plastic model of his yellow Simpsons incarnation had pride of place in his house.”

The lot also includes medals and a thumbprint-signed copy of A Brief History of Time, which is expected to get between £2,000 and £3,000. Titled On The Shoulders of Giants, the auction will also include items once owned by Isaac Newton, Albert Einstein and Charles Darwin.

The online auction will run from October 31 to November 8.
