Frederich H. Heider

Fritz Heider (1896–1988) was an Austrian-born American social psychologist renowned for developing attribution theory and balance theory, which explore how people perceive and interpret social behaviors and relationships. Initially studying architecture, he shifted to psychology, influenced by Gestalt psychologists, and immigrated to the United States in 1930, where he conducted pioneering research at the Clarke School for the Deaf and later as a professor at the University of Kansas. His seminal 1958 book, *The Psychology of Interpersonal Relations*, solidified his lasting impact on social psychology.[1][2][4]
