Stephen Hawking, perhaps the best known scientist in the world, died, confirmed a spokesman for his family. He was 76 years old.
"It is with great sadness that we announce the death of Professor Stephen Hawking CH CBE FRS FRSA at the age of 76," the statement said. "Professor Hawking died peacefully at his home in Cambridge early in the morning, his family has kindly requested that they be given the time and privacy to mourn his passing, but would like to thank everyone who has been there. Professor Hawking and they have supported him throughout his life. "
Hawking was born on January 8, 1942 in Oxford, England. His best-known work included his collaboration with Roger Penrose on gravitational singularities, the prediction that black holes emit black-body radiation and the best-seller A Brief History of Time. The book aimed to present key cosmological concepts to a non-specialized audience, and sold more than 10 million copies in 20 years.
Hawking was diagnosed with a motor neuron disease, or ALS, at the age of 21. The debilitating disease gradually paralyzed him, confining him to a wheelchair, and in 1985, a tracheotomy stole his voice. But Hawking continued to be a hugely prominent and popular public figure through the use of his computer-assisted voice system, which required careful operation by a single cheek muscle.
"My disability has not been a significant disadvantage in my field, which is theoretical physics – in fact, they have helped me in some way," Hawking once wrote, saying that his situation gave him time to think clearly about the problems of physical. And Hawking not only far exceeded the expectations of doctors, but he rose to the top of his field, becoming a great celebrity in the process. He appeared in The Simpsons and an Oscar-winning film, The Theory of Everything, was made during a period of his life.
"We are deeply sad because our beloved father passed away today," Hawking's children Lucy, Robert and Tim said in a statement. "He was a great scientist and an extraordinary man whose work and legacy will last for many years." His courage and persistence with his brilliance and humor inspired people from all over the world, He once said: "It would not be much of a universe if it were not home of the people you love. "We will miss him forever."
