British scientist Stephen Hawking is dead, announces a statement from his family.
British theoretical physicist Stephen Hawking died at the age of 76, the British Press Association reported on Tuesday, citing a spokesman for the family. Born in Oxford in the United Kingdom, he died at home in Cambridge.

“We are deeply saddened by the death of our beloved father today.” “He was a great scientist and an extraordinary man whose work will live for many years,” wrote his children Lucy, Robert and Tim in a text also published by the British agency Press Association.
Nailed in a chair and speaking through a computer, Stephen Hawking devoted his life to unlocking the secrets of the universe and popularizing astrophysics, to the point of becoming a star.
Push the limits
“I’m sure my disability has something to do with my celebrity. People are fascinated by the contrast between my very limited physical abilities and the extremely wide nature of the universe I’m studying, “said the contemporary scientist, certainly the most famous in the world.
Stephen Hawking was born in Oxford on January 8, 1942, 300 years to the day after Galileo’s death.
His father, a biologist, wants him to follow his steps by studying medicine in Oxford. But young Stephen has already taken a passion for mathematics. This subject is not taught in the prestigious university, he opts for physics. After three years, he left for Cambridge to pursue research in astronomy.
Shortly after his 21st birthday, he learns that he suffers from paralytic degenerative disease, amyotrophic lateral sclerosis (ALS) or Charcot’s disease.
Doctors give him only two years to live. Not even knowing if he will be able to complete his doctoral thesis, he is plunged into a deep depression, from which he only comes out thanks to his meeting with a linguistics student, Jane Wilde, whom he married in 1965.
The couple, who divorced 30 years later, will have three children. Stephen Hawking will marry Elaine Mason for the second time, after eleven years in 2006.
His body declines inexorably. In 1974, he was unable to feed himself or get out of bed on his own. In 1985, he definitively lost the use of speech after undergoing tracheotomy following pneumonia.
“Completely understand the universe”
But his mind is intact. And his simple goal: “to completely understand the universe, why he is as he is and why he exists”.
In the 1970s, he developed the idea that black holes do not just absorb any matter and light passing near them but also emit radiation, the “Hawking radiation”.
In doing so, he is the first to reach out to the grail of physicists: to begin to reconcile the two great theories that explain the functioning of the universe and are apparently incompatible, namely the general relativity of Einstein for the infinitely great and quantum mechanics for the infinitely small.
In the opinion of the scientists, this theory would have earned Stephen Hawking the Nobel Prize if it could have been experimentally demonstrated.
In the footsteps of Newton
At 32, he became the youngest member of the Royal Society, the British equivalent of the Academy of Sciences.
In 1980, he was awarded the Lucasian Chair in Mathematics at Cambridge University, a post he held before him by Isaac Newton. He will leave in 2009, struck by the age limit.
While deepening his work on the origins of the universe, the theorist published in 1988 “A brief history of time,” to explain to the general public the great principles of cosmology, the Big Bang to string theory.
Never a book of popular science will be so successful. Since its publication, more than nine million copies have been sold.
Stephen Hawking then becomes the popular incarnation of the scientist, multiplying the interventions to promote the research and, sometimes, to worry about its possible excesses.
Formidable communicator, able to perform a weightless flight despite his disability, he lends himself to the game with a certain pleasure and a great sense of humor. His Facebook page that he feeds himself with messages signed “SH” has more than 4 million “friends”.
He plays his own part in series like “Star Trek”, “The Big Bang Theory” and “The Simpsons”, signs children’s books with his daughter Lucy, “sings” with his synthetic voice alongside U2, Pink Floyd and even Monthy Python.
A year ago, he appeared at a conference
