Pete Seeger (May 3, 1919 - January 27, 2014) was an American folk singer, political activist and author, and a key figure in the mid-20th century American folk music revival. He is particularly loved as the author (or co-author) of the songs Where Have All the Flowers Gone, If I Had a Hammer, and Turn, Turn, Turn. One of his brothers is Mike Seeger; Peggy Seeger is his half-sister. As a member of The Weavers, Seeger had a string of hits, including a 1949 recording of Leadbelly's "Goodnight Irene" that topped the charts for 13 weeks in 1950.
