Hans Eysenck was born in Germany to parents who were both noted film and stage actors. After his parents' divorce when he was only two, he was raised almost entirely by his grandmother. His antipathy toward Hitler and the Nazi's led him to move to England when he was 18. Because of his German citizenship, he found it difficult to find work in England. He eventually went on to earn a Ph.D in Psychology from the University College London in 1940 under the supervision of psychologist Cyril Burt, perhaps best-known for his research on the heritability of intelligence.

During the Second World War, Eysenck worked as a researcher psychologist at Mill Hill Emergency Hospital. He later founded the psychology departed at the University of London Institute of Psychiatry, where he continued to work until 1983. He served as Professor Emeritus at the school until his death in 1997. He was also an extremely prolific writer. Over the course of his career, he published more than 75 books and over 1600 journal articles. Prior to his death, he was the most frequently cited living psychologist.

In addition to being one of the most famous psychologists, he was also one of the most controversial. One of the earliest controversies revolved around a paper he wrote in 1952 on the effects of psychotherapy. In the paper, Eysenck reported that two-thirds of therapy patients improved significantly or recovered within two year, regardless of whether or not they received psychotherapy.

He was also a vocal critic of psychoanalysis, dismissing it as unscientific. You can hear Eysenck describe his views on Freudian theory and psychoanalytic treatment in this video: Hans J. Eysenck, Ph.D. Lifetalk with Roberta Russell on Psychoanalysis

The greatest controversy surrounding Eysenck was his view of the heritability of intelligence, more specifically his view that racial differences in intelligence could be partially attributed to genetic factors. After one of his student's was criticized for publishing a paper suggesting that genetics were responsible for racial differences in intelligence, Eysenck defended him and later published The IQ argument: Race, Intelligence, and Education, which incited considerable controversy and criticism. His 1990 autobiography took a more moderate view that ascribed greater importance to the role of environment and experience in shaping intelligence.

While Hans Eysenck was certainly a controversial figure, his wide-ranging research had a major influence on psychology. In addition his work in personality and intelligence, he also played a major role in establishing approaches to clinical training and psychotherapy that were firmly rooted in empirical research and science.
