Woodrow Wilson "Woody" Guthrie (July 14, 1912 – October 3, 1967) was an American singer-songwriter and musician whose musical legacy includes hundreds of political, traditional and children's songs, ballads and improvised works. He frequently performed with the slogan This machine kills fascists displayed on his guitar. His best-known song is "This Land Is Your Land." Many of his recorded songs are archived in the Library of Congress. Songwriters such as Bob Dylan, Phil Ochs, Bruce Springsteen, Robert Hunter, Harry Chapin, John Mellencamp, Pete Seeger, Andy Irvine, Joe Strummer, Billy Bragg, Jerry Garcia, Jay Farrar, Bob Weir, Jeff Tweedy, Bob Childers and Tom Paxton have acknowledged Guthrie as a major influence. Many of his songs are about his experiences in the Dust Bowl era during the Great Depression when Guthrie traveled with displaced farmers from Oklahoma to California and learned their traditional folk and blues songs, earning him the nickname the "Dust Bowl Troubadour." Throughout his life Guthrie was associated with United States Communist groups, though he was seemingly not a member of any. Guthrie was married three times and fathered eight children, including American folk musician Arlo Guthrie. Guthrie died from complications of Huntington's disease, a progressive genetic neurological disorder. During his later years, in spite of his illness, Guthrie served as a figurehead in the folk movement, providing inspiration to a generation of new folk musicians, including mentor relationships with Ramblin' Jack Elliott and Bob Dylan.
