Stephen Hawking

Scientists, politicians and actors have paid tribute to world renowned physicist Stephen Hawking, who has been called an "inspiration to millions".

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 21 and was told he had only a few years to live.

He was known for his theories on black holes and relativity and went on to publish several popular science books including A Brief History of Time.

The University of Cambridge, where Prof Hawking completed his PhD and went on to become Lucasian Professor of Mathematics - a role once held by Sir Isaac Newton - described him as "an inspiration to millions".

Queues have formed at Gonville and Caius College - where Prof Hawking was a fellow for more than 50 years - to sign a book of condolence.

Buckingham Palace said the Queen will be sending a message of condolence to Prof Hawking's family.

Prof Hawking's children, Lucy, Robert and Tim, said in a statement: "His courage and persistence with his brilliance and humour inspired people across the world.

"He once said, 'It would not be much of a universe if it wasn't home to the people you love'. We will miss him forever."
