- 2015 – Marshall Rosenberg, American psychologist and author (b. 1934).
Alfred Adler (07 February 1870 to 28 May 1937) was an Austrian medical doctor, psychotherapist, and founder of the school of individual psychology. His emphasis on the importance of feelings of inferiority, the inferiority complex, is recognised as an isolating element which plays a key role in personality development. Alfred Adler considered a human being as an individual whole, therefore he called his psychology “Individual Psychology” (Orgler 1976).
Adler was the first to emphasize the importance of the social element in the re-adjustment process of the individual and who carried psychiatry into the community. A Review of General Psychology survey, published in 2002, ranked Adler as the 67th most eminent psychologist of the 20th century.
Marshall Bertram Rosenberg (06 October 1934 to 07 February 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 Centre for Nonviolent Communication, an international non-profit organisation for which he served as Director of Educational Services.
