The British physicist was known for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.
“We are deeply saddened that our beloved father passed away today,” a family statement said.
At the age of 22 Stephen Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.
