Marshall 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[1] founded the Center for Nonviolent Communication, an international non-profit organization[2] 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."
