Marshall B. Rosenberg

Marshall Bertram Rosenberg (October 6, 1934 – February 7, 2015) was an American psychologist, mediator, author and teacher. Starting in the early 1960s, he developed nonviolent communication, a process for supporting partnership and resolving conflict within people, in relationships, and in society. He worked worldwide as a peacemaker and in 1984, founded the Center for Nonviolent Communication, an international nonprofit organization for which he served as Director of Educational Services. According to his biographer, Marjorie C. Witty, "He has a fierce face – even when he smiles and laughs. The overall impression I received was of intellectual and emotional intensity. He possesses a charismatic presence."
