it would be a fitting end for such an important person to science.
If you mention his name, plenty of people will say "that's the smart guy in the wheelchair with the funny voice", but very few of them would know about anything that he has done. He theorized that black holes emit radiation, and came up with some hypothesis about quantum gravity
I thought he was the one who in university made the Big Bang hypothesis work out in mathematics for the first time (maybe along with Roger Penrose). This is kind of an important thing in cosmology and in my books puts him amongst the greats like Feynman, Bohr, et al before him. Of course we also have Hawking radiation named after him and all the other stuff that you mention.
