Dr. Theodore Millon

Theodore Millon, PhD, DSc,(1928-2014) received his PhD from the University of Connecticut in 1954. Renowned for his APA-award winning work, Dr. Millon’s evolutionary theory of personality and psychopathology led to the development of multiple widely-used measures that help to define how scientists and psychologists identify and think about personality disorders today.
