Peter Yarrow was an American singer and songwriter who found fame as a member of the 1960s folk trio Peter Paul & Mary. Yarrow co-wrote (with Lenny Lipton) one of the group's best known hits, "Puff, the Magic Dragon." He was also a political activist and supported causes that ranged from opposition to the Vietnam War to school anti-bullying programs. Yarrow was convicted in 1970 of molesting a 14-year-old girl, for which he was pardoned in 1981 by President Jimmy Carter.
