Woodrow Wilson Guthrie (July 14, 1912 – October 3, 1967) was an American singer-songwriter and composer who was one of the most significant figures in American folk music. His work focused on themes of American socialism and anti-fascism. He inspired several generations both politically and musically with songs such as "This Land Is Your Land". Guthrie wrote hundreds of country, folk, and children's songs, along with ballads and improvised works. Dust Bowl Ballads, Guthrie's album of songs about the Dust Bowl period, was included on Mojo magazine's list of 100 Records That Changed The World, and many of his recorded songs are archived in the Library of Congress. Songwriters who have acknowledged Guthrie as a major influence on their work include Bob Dylan, Phil Ochs, Johnny Cash, Bruce Springsteen, Robert Hunter, Harry Chapin, John Mellencamp, Pete Seeger, Andy Irvine, Joe Strummer, Billy Bragg, Jerry Garcia, Bob Weir, Jeff Tweedy, Tom Paxton, Brian Fallon, Sean Bonnette, and Sixto Rodríguez. He frequently performed with the message "This machine kills fascists" displayed on his guitar.
