A red motorized wheelchair once used by Stephen Hawking has sold more than $ 500,000 at a charity auction in London.
- Many of Professor Hawking's personal details and academic papers were sold at auction
- A lot included a script from Simpson's appearance
- The proceeds went to the Stephen Hawking Foundation and the Motor neuron disease disease
Items belonging to the late physicist and guest star repeat the Simpsons went under a hammer at a sale held by Christie's auction house on Thursday.
Professor Hawking, who lived in motor neuron disease, was confined to a wheelchair for most of his career, requiring an electronic voice synthesizer to communicate. He died in March 2018.
A wheelchair he used in the late '80s and early' 90s sold more than $ 543,000 in the auction to raise money for the Stephen Hawking Foundation and the Neuron Foundation for Disease.
He used the wheelchair while he still had the ability to control his movements, using a joystick to navigate himself.
Hawking's extraterrestrial use of his wheelchair became legendary after crossing the fingers of Prince Charles during a meeting in 1977.
He was rumored to focus the toes of those who harassed him, a claim he referred to in his trademark humor.
"Malicious rumor," he told Super Kitty Ferguson.
"I'll want those who repeat it."
Letters and Manuscripts by Isaac Newton, Charles Darwin and Albert Einstein were also sold together with a number of Professor Hawking's works, medals and prizes.
Hawking's Hawking 117 doctoral thesis, from 1965, was sold for just over $ 1 million, putting it above $ 270,000.
An invitation to a party for time travelers, led by Professor Hawking to prove that time travel does not exist, was sold for more than $ 20,000.
The buyers were also interested in an original script for the Simpsons episode, starring Professor Hawking, who brought in more than $ 11,000.
Buyers placed their offers online, with an auction proving very popular.
"Stephen Hawking was a huge personality around the world," said Christie's head of books and reporters in London.
"He had an amazing ability to connect with people."
Professor Hawking was diagnosed with motor neuromuscular disease at the age of 22 when doctors said he had only years to live.
However, he went to live until the age of 76, with his death mourned around the world earlier this year.
Despite his illness, Professor Hawking continued to revolutionize theories about back holes and the origins of the universe, and wrapped popular titles such as "A Brief History of Time."
His work was not only a sign of the world of science, but his sense of humor saw him as a symbol of pop culture.
Professor Hawking's latest book, short answers to the big questions, was launched last month.
His daughter, Lucy Hawking, told ABC the 7.30 report that her father wanted to see unity in humanity.
"I think one thing that really bothers him is the nature of the challenges that the world faces today and they are global and we are busy dividing ourselves, they are more and more broken, more divided, more and more angry," she said.
