Alexander Mitscherlich was a German psychologist who studied how people in groups behave. He was interested in how people are influenced by the people that they are around and how group dynamics shape our lives. He found that people who are in groups often act differently from how they would act when they are alone. He also studied how people interact in a work situation, and he thought that when people work in teams they can be more successful than if they work alone. He believed that if people have a feeling of trust, freedom, and respect in the workplace, they can do their best work. He also wrote extensively about guilt, mourning and collective memory.
