The Jesus/Abraham/Muhammad/Vishnu/Buddha/Ra/Odin/Zeus/Jupiter/Mormon Jesus of prog... Robert Fripp.
His talent lies not only in how good of a songwriter he was and his technical ability. But he also knew when to step back and let his band mates take the lead. Considering the quality of King Crimson's work in spite of all the line-up changes and him being the only constant, he gain a ton of credit just with one of his musical pursuits alone. Between the work with Brian Eno, Andy Summers, The Talking Heads, David Bowie and even Microsoft (perhaps the only redeeming feature of Vista was he designed the soundscapes and noises) and Frippertronics, the man is a genius in my book and has my vote.
Not bad for a guy who looks like your math teacher...
