Peter Seeger (born May 3, 1919) almost universally known as "Pete Seeger", is a folk singer and political activist. As a member of the Weavers, he had a string of hits, including a 1949 recording of Leadbelly's "Goodnight Irene" that topped the charts for 13 weeks in 1950. He was a major contributor to folk and pioneer of protest music in the 1950s and the 1960s.
He is perhaps best known today as the author or co-author of the songs "Where Have All the Flowers Gone", "If I Had a Hammer", and "Turn, Turn, Turn", which have been recorded by many artists both in and outside the folk revival movement and which are still sung all over the world. "Flowers" was a hit recording for The Kingston Trio (1962), Marlene Dietrich, who recorded it in English, German and French (1962), and Johnny Rivers (1965). "If I Had a Hammer" was a hit for Peter, Paul & Mary (1962) and Trini Lopez (1963), while The Byrds popularized "Turn, Turn, Turn" in the mid-1960s.
