Who's the real "prototype for the sexy geek"?

Some Entertainment Weekly editors are saying it's Seth Green, who seems to think it might be Weird Al. But that's because EW is interviewing Seth Green, and Seth Green just got done interviewing Weird Al. Nevertheless, it's a great -- or good enough! -- question to justify trying to come up with a list and then narrow it down for a vote. You're not limited to actors and musicians, and remember the key word is prototype. Who originally unleashed the possibility that we could see the geek as sexy? I think that means going back a long, long way. But keep the time frame within reason -- at least within the era of photography. We don't need to hear about what Alcibiades said about Socrates in "The Symposium." And frankly, it would be geeky to bring that up. Not even geeky. Nerdy.
