Iconic Physicist Stephen Hawking Dies At 76


Stephen Hawking died Wednesday after complications due to amyotrophic lateral sclerosis, a progressive neurodegenerative disease. He was 76.

The world-renowned theoretical physicist and cosmologist was best known for his work on black holes. Hawking theorized that, contrary to the prevailing scientific belief that black holes were inescapable for all forms of matter and energy, they actually emitted a form of radiation ― now known as Hawking radiation. He also played a key role in the mathematical effort to unify Einstein’s general theory of relativity with the emergent field of quantum physics.

Hawking used his position as one of the world’s most famous scientists as a platform to discuss a wide range of issues, from the existence of extraterrestrial life to the nature of philosophy. He skyrocketed to public prominence in 1988, when he published his first general-audience book, A Brief History of Time: From the Big Bang to Black Holes. The cosmology treatise has sold approximately 10 million copies worldwide, making it one of the best-selling science books of all time.

The physicist’s inspiring ― and turbulent ― personal story was dramatized in the 2014 movie “The Theory of Everything,” which was based on a memoir by Hawking’s first wife, Jane Wilde. Actor Eddie Redmayne’s portrayal of Hawking in the film won him an Oscar for best actor.

At the St. Albans School, Hawking was an indifferent student, preferring to spend his time playing board games and tinkering with computers. But he nonetheless gained admittance to his father’s alma mater, University College at Oxford University, in 1959, at the age of 17.

Upon arriving at Oxford, Hawking toyed with the idea of studying either math or medicine before eventually settling on physics. His attitude toward academic work remained lackadaisical in college. He rarely attended lectures and has said that he spent only 1,000 hours on studies during his three years at Oxford, or just an hour a day.

Still, Hawking’s natural brilliance started to shine through as an undergraduate ― and he apparently felt that his tutors resented him for doing so well with so little work. When he submitted his final thesis, it was given a grade on the border between first-class honors and second-class honors, so Hawking had to face an oral exam that would determine his grade. Knowing his reputation, he reportedly told his examiners, “If you award me a First, I will go to Cambridge. If I receive a Second, I shall stay in Oxford, so I expect you will give me a First.”

He got a First. And, as promised, Hawking enrolled in graduate school at Trinity College, Cambridge in 1962, studying under the physicist Dennis Sciama and the famed astronomer Fred Hoyle. He became interested in the then-nascent study of black holes and singularities, the existence of which had been implied by Einstein’s general theory of relativity.

While studying at Cambridge, Hawking met Wilde, a fellow St. Albans native who was a student in modern languages at Westfield College in London at the time. Before the two started dating, Hawking collapsed while ice skating and couldn’t get up. His mother made him go to the doctor, who diagnosed him with ALS and estimatedhe had just over two years to live.

Years later, during a symposium at Cambridge on his 70th birthday, Hawking reflected on how much he struggled to stay motivated after his diagnosis. Why work so hard for a Ph.D. when you could be dead in two years?

However difficult life may seem, there is always something you can do, and succeed at. It matters that you don’t just give up. Stephen Hawking, as he celebrated his 70th birthday

“Remember to look up at the stars and not down at your feet,” he said. “Try to make sense of what you see and about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do, and succeed at. It matters that you don’t just give up.”

Hawking’s motor control deteriorated rapidly; he was soon walking to class on crutches. Yet the disease spurred him to deepen his relationship with Wilde quickly. They married in 1965.

After receiving his doctorate in cosmology, Hawking stayed at Cambridge to continue studying some of the most essential questions about the structure of the universe. In 1968, a year after Jane gave birth their eldest son, Roger, Hawking took a post at the Institute of Astronomy at Cambridge and began the mature phase of his academic career.

Over the next decade, Hawking published a string of groundbreaking papers on cosmology and theoretical physics that made him a celebrity in the scientific community.

Soon after publishing his paper, Hawking, just 32 years old, was named a fellow of the prestigious Royal Society. He briefly taught at the California Institute of Technology before assuming the position of Lucasian Professor of Mathematics at Cambridge, a post dating back more than 400 years that was once held by Isaac Newton.

Though Hawking’s family life flourished during this time ― he and Jane Hawking went on to have two more children ― his health did not. He reluctantly started using a wheelchair in 1969, and by the mid-70s, he could no longer feed or clothe himself.

Hawking first came up with the idea of writing a book about cosmology for a general audience in 1982. He said he conceived of the project to “earn money to pay [his] daughter’s school fees.” The first draft of A Brief History of Time was finished in 1984, but Hawking’s publisher felt it was too difficult for laypeople to understand, so he went back to work. The revision process became more complicated after Hawking lost his voice in 1985, but he managed to publish the book in 1988.

It was a massive hit: The book was on The New York Times’ best-seller list for three years and The Sunday Times’ U.K. best-seller list for nearly five. Its publication propelled Hawking to international fame that’s endured to this day. He published five additional general-audience books on science, plus one memoir and four children’s books. He also guest-starred on both “The Simpsons” and “Star Trek: The Next Generation.”

Stephen and Jane Hawking separated after several years of tension in 1990, which Jane said was exacerbated by her husband’s newfound ” fame and fortune.” The physicist began a relationship with Elaine Mason, one of his nurses. After his divorce from Jane Hawking, he married Mason in 1995.

In 2011, Hawking appeared on the Discovery Channel TV series “Curiosity,” in which he reflected on the origins of the universe and rejected the likelihood of both a God and an afterlife. ( He once dismissed the latter as “a fairy story for people afraid of the dark.”) Only in confronting the finite nature of death, he said, do we appreciate the remarkable beauty of life in the present.

“There is probably no heaven, and no afterlife either,” Hawking said. “We have this one life to appreciate the grand design of the universe, and for that, I am extremely grateful.”

In addition to his two former wives, Hawking is survived by three children and three grandchildren.
