It's no exaggeration to say that Pete Seeger has done more to popularize American folk music than any other contemporary musician, authoring or co-authoring the songs that have become folk standards: If I Had a Hammer, Where Have All the Flowers Gone? and Turn! Turn! Turn! to name just a few. His work has inspired countless musicians including Joan Baez, Bob Dylan, Bruce Springsteen and the Dixie Chicks, and his tireless political and environmental activism have galvanized generations of admirers to follow his lead and take action.
