Stephen Hawking arguably the most celebrated theoretical physicist and cosmologist in the world passed away early Wednesday morning local time, at his home in Cambridge, England.
He was 76.
Despite being diagnosed in his twenties with Lou Gehrig's disease, he continued to live and pursue what physicists call a "unified theory" of everything.
Hawking first came to prominence through his research on black holes in the 1970s.
He became a celebrity of sorts through his best-selling books and appearances on television.
Many will agree his courage, persistence, brilliance and humour has and will continue to inspire people across the world.
