Without Pete Seeger, American folk music as we know it today would be radically different. Seeger was one of modern folk's earliest and most significant architects, from his work in the 1940s with the Almanac Singers (of which Woody Guthrie was a member) and the famed Weavers, to his voice-of-a-generation political music of the 1960s and beyond. He helped adapt America's earliest musical traditions to a politicized post-war environment. In addition to his legendary songs of protest, civil rights, and environmentalism, Seeger is well known for creating children's music.
