Peter Seeger (born May 3, 1919), almost always known as Pete Seeger, is a folk singer, political activist and major contributor to folk and protest music in 1950s and 1960s. His father Charles Seeger was a musicologist and an early investigator of non-Western music. His siblings Mike Seeger and Peggy Seeger also had notable musical careers.
Pete Seeger started a solo career in 1958 (see 1958 in music), and is known for songs such as "If I Had a Hammer" (co-written with Lee Hays), "Turn, Turn, Turn" (adapted from Ecclesiastes), and "We Shall Overcome" (based on a spiritual).
In he 1960s, Seeger wrote the first version of his now-classic "How to Play the Five-String Banjo", a book that many banjo players credit with starting them off on the instrument.
Pete Seeger is involved in the Clearwater group, which he helped found in 1966. This organization has worked since then to highlight pollution in the Hudson River and work at getting it cleaned up. As part of that effort, the sloop Clearwater was launched in 1969 and regularly sails the river as a classroom, stage and laboratory.
Pete Seeger is also well known for his communist political beliefs.
