Cambridge Professor Stephen Hawking has provided a posthumous windfall for two charities.
One of the theoretical physicist's wheelchairs was sold at auction smashing its estimate. The wheelchair was expected to go for £10-15,000. In fact it went for close to £300,000.
The money from the wheelchair will benefit two charities 'The Stephen Hawking Foundation' which he founded in 2015 and The Motor Neurone Disease Association. When the physicist died in March this year he'd lived with the condition for over fifty years.
Other items sold by auction house Christies include his dissertation, which fetched over half a million pounds, and his bomber jacket that went for £40,000.
And quirky items included an invitation to a party he held in 2009 where nobody turned up - because the invites were only for time travellers and the event was publicised after it happened. It sold for £11,000.
The way Hawking reached younger people encouraging their interest in science also struck a chord with buyers. A script from one of his appearances on The Simpsons was snapped up for £6,000; proving the theory his legacy is as infinite as the universe he explored.
