Peter Yarrow, a Grammy-award winner, has been a long time advocate for social change, reaching back to his involvement in festivals for peace and the 1969 anti-war March on Washington in which some half million people participated. In an effort to combat school violence, he has focused his energy on projects reaching out to youth and communities through Operation Respect, a nonprofit organization he founded in 1999 to combat bullying ridicule and violence in schools. It offers curriculum to children as young as pre-schoolers and continuing through grade school and later.
