Pete Seeger, American singer-songwriter, guitarist, and activist (died 2014)

Peter Seeger was an American singer, songwriter, musician, and social activist. He was a fixture on nationwide radio in the 1940s and had a string of hit records in the early 1950s as a member of The Weavers, notably their recording of Lead Belly's "Goodnight, Irene", which topped the charts for 13 weeks in 1950. Members of the Weavers were blacklisted during the McCarthy Era. In the 1960s, Seeger re-emerged on the public scene as a prominent singer of protest music in support of international disarmament, civil rights, workers' rights, counterculture, environmental causes, and ending the Vietnam War.
