Daniel Berrigan, anti-Vietnam War activist, poet, and Catholic priest, spoke on "A Peacemaking Citizen in a Warmaking State" in the Villard Room.   Along with his brother Philip—also a Catholic priest—and six others, Berrigan formed the Plowshares Movement in 1980, attacking a nuclear missile factory in Pennsylvania and damaging materiel and files, the first of his many of non-violent anti-war and human rights actions over decades and around the world.
