The British scientist, famed for his work on black holes, died peacefully at his home in Cambridge aged 76.

Astronomer Royal Lord Rees, one of the world's most eminent scientists, described his life as a "triumph".

Others described him as a "unique individual" whose death "has left an intellectual vacuum in his wake".

Prof Hawking was diagnosed with a rare form of motor neurone disease at the age of 22 and was told he had only a few years to live.
