Seeger, a Woody Guthrie protege whose songwriting credits included folk classics "Where Have All the Flowers Gone" and "Turn! Turn! Turn!," died of natural causes at New York-Presbyterian Hospital, his grandson Kitama Cahill Jackson told the New York Times and the Associated Press.



Seeger also was known for his liberal politics, working as an environmentalist, protesting against wars from Vietnam to Iraq and being sentenced to prison for refusing to testify to Congress about his time in the Communist Party. The case was dismissed years later.
