A wheelchair used by the late Professor Stephen Hawking and a copy of his doctoral thesis have fetched almost £1m between them at auction.

The motorised chair – which had a pre-sale estimate of £15,000 – went for a whopping £296,750, with the proceeds donated to his foundation and the Motor Neurone Disease Association.

His 1965 Cambridge University thesis – Properties of Expanding Universes – attracted even bigger bids and eventually sold for £584,750.

Professor Hawking’s daughter, Lucy, said the sale gave “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”.

The celebrated scientist – who was diagnosed with motor neurone disease at the age of 22 – died in March.

Despite being given just two years to live after being diagnosed with the disease, Professor Hawking had a long, accomplished and inspiring career.

His most notable work was A Brief History Of Time, which became a huge hit upon its publication in 1988 – selling 10 million copies and being translated into 35 languages.
