Stephen Hawking, the British theoretical physicist has died at the age of 76.
A spokesman for his family confirmed his death to The Associated Press.
Hawking was as famous for his insights on black holes, the existence of God and quantum gravity as he was for his unique way of speaking while living his life in a wheelchair.
Hawking was diagnosed at age 21 with amyotrophic lateral sclerosis (ALS).
Operating his trademark computer system with his cheek, Hawking gave the world insights into the unknown and gems of quotations, including, "Life would be tragic if it weren't funny."
