Cosmologist and physicist Stephen Hawking, known for his discoveries on the nature of black holes and scientific work on the origins of the universe, died yesterday at the age of 76.

Although in a wheelchair for most of his life, he was one of science's brightest stars and changed the way humans view the universe, said scientists and world leaders who paid tribute to him.

His family confirmed his death in a statement, saying his work and legacy will live on for many years: "His courage and persistence, with his brilliance and humour, inspired people... 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."
