Peter Yarrow is an American singer who found fame with the 1960s folk music trio Peter, Paul and Mary. Yarrow co-wrote "Puff, the Magic Dragon." He is also a political activist and has lent his support to causes that range from opposition to the Vietnam War to the creation of Operation Respect. He believes “in shifting the American educational paradigm to educating the whole child; not just in academics but in character, heart, social-emotional development."
Founded by Peter Yarrow, Operation respect disseminates educational resources that are designed to establish a climate that reduces the emotional and physical cruelty some children inflict upon each other by behaviors such as ridicule, bullying and-in extreme cases-violence. - http://www.operationrespect.org/index2.php
