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, relationships, and 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.
