Renowned physicist Stephen Hawking has died.
Stephen Hawking – who died aged 76 – battled motor neurone disease to become one of the most respected and best-known scientists of his age.
A man of great humour, he became a popular ambassador for science and was always careful to ensure that the general public had ready access to his work.
His book A Brief History of Time became an unlikely best-seller although it is unclear how many people actually managed to get to the end of it. . .
