Warren Norman

Warren T. Norman (1930–1998) was a psychologist recognized for his research on personality psychology, particularly in establishing the Five-Factor Model (FFM), also known as Norman's "Big 5". These dimensions, extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience, are foundational aspects of contemporary personality theory. He was the Head of the Department of Psychology at the University of Michigan and worked there for thirty seven years.

Education Norman earned degrees from the University of Minnesota, obtaining a Bachelor of Science in Mathematics and Natural Science in 1952. In 1955 he earned a Master of Arts in Statistics and Educational Psychology, followed by a Ph.D. in Psychology in 1957.

Rounding out a productive 1963, he published his most well-known work, the Five-Factor Model (FFM).

Throughout his career he served in many leadership positions for psychology societies, journals, and organizations. He also worked at the Oregon Research Institute, the University of Birmingham in England, as well as the University of Queensland and University of Western Australia. He was the 1971 president of the Society of Multivariate Experimental Psychology (SMEP).
