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.
In 1963, when he was just 21 years old, Hawking was famously diagnosed with the debilitating motor neuron disease amyotrophic lateral sclerosis. Though 80 percent of those with ALS die within five years of diagnosis, and Hawking’s own doctors gave him roughly two years to live, he survived for decades, perhaps longer than any other patient with the disease in medical history.
