Hans Eysenck was born in Berlin, Germany on March 4, 1916. In 1940 he received his Ph.D in psychology from the University of London. Eysenck worked as a Professor of Psychology at the Institute of Psychiatry, King's College, London, from 1955 to 1983. He was a major contributor to the modern scientific theory of personality.

Definition of Personality
According to Hans Eysenck, personality is the sum-total of the actual or potential behavior-patterns of the organism, as determined by heredity and environment. It originates and develops through the functional interaction of the four main sectors into which these behavior-patterns are organized". In other words, personality is one's whole character and nature. Simply speaking, it is what makes who you are and what makes what you do.
Eysenck's Personality Types Theory
Eysenck initially conceptualized personality as two, biologically-based categories of temperament: Extraversion/Introversion and Neuroticism/Stability. The two dimensions or axes, extraversion-introversion and emotional stability-instability, define four quadrants.
- High N and high E = Choleric type (unstable extraverts) : qualities such as - touchy, restless, excitable, changeable, impulsive, irresponsible.
- High N and low E = Melancholic type (unstable introverts): qualities such as - quiet, reserved, pessimistic, sober, rigid, anxious, moody.
- Low N and high E = Sanguine type (stable extraverts): qualities such as - outgoing, talkative, responsive, easygoing, lively, carefree, leadership).
- Low N and low E = Phlegmatic type (stable introverts): qualities such as - calm, even-tempered, reliable, controlled, peaceful, thoughtful, careful, passive.
