Though not history's most impressive nerd, Bill Gates has come to quintessentially represent our modern concept of geekdom. His bespectacled face and quirky mannerisms are famous across the world.

Gates has a long-running rivalry with Larry Ellison of Oracle. When Gates bought an F16, Ellison attempted to buy a MiG. And let us not forget he is now one of the world's most generous philanthropists.
Turing is regarded as one of the greatest cryptographers to have ever lived. Not only did he crack many German ciphers during the war, but he cracked the Enigma machine -- thought at the time to be an impossible task. Forget Kevin Mitnick, Turing was a far superior cracker -- he also invented the Turing machine, a forerunner to the modern microcomputer. Turing was hounded by authorities who were intolerant of his homosexuality. He died in 1954, apparently after eating an apple laced with cyanide.

And the grand winner, the greatest and geekiest of all is...
