Jonathan Coulton (born December 1, 1970) is an American singer-songwriter, known for his songs about geek culture and his use of the Internet to draw fans. Among his most popular songs are "Re: Your Brains" and "Still Alive".
A former computer programmer and self-described geek, Coulton tends to write quirky, witty lyrics about science fiction and technology: a man who thinks in simian terms, a mad scientist who falls in love with one of his captives, and the dangers of bacteria. Rare topical songs include 2005's "W's Duty", which sampled President George W. Bush, and 2006's "Tom Cruise Crazy". Most of Coulton's recordings feature his singing over guitar, bass, and drums; some also feature the various other instruments Coulton plays, including accordion, harmonica, mandolin, banjo, ukulele, and glockenspiel.
Coulton graduated in 1993 from Yale, where he was a member of the Yale Whiffenpoofs and the Yale Spizzwinks(?). He is now the Contributing Troubadour at Popular Science magazine, whose September 2005 issue was accompanied by a five-song set by him called Our Bodies, Ourselves, Our Cybernetic Arms. He was also the Musical Director for The Little Gray Book Lectures.
