Alfred Adler

Alfred Adler (1870 - 1937) was a famous Viennese psychologist who split with Sigmund Freud. Thereafter he termed his school of psychology "individual psychology" to distinguish it from Freud's psychoanlysis. Adler coined the terms "inferiority complex" and "superiority complex."

• Adler "maintained that personality difficulties are rooted in a feeling of inferiority deriving from restrictions on the individual's need for self-assertion." [1]
