Raymond Cattell

Early Life and Education

Raymond Bernard Cattell was born on 20 March 1905 in Hill Top, West Bromwich, a small town in England. His parents, Herbert and Elizabeth Cattell, were both avid music enthusiasts, which influenced Cattell's early interest in the arts and sciences. He attended the University of London, where he studied chemistry and physics, earning his degree in 1924.

During his time at the university, Cattell developed a keen interest in psychology, particularly in the works of Francis Galton and Charles Spearman. This led him to pursue further studies in the field of psychology. He completed his Ph.D. in psychology at the University of London in 1929, under the supervision of Charles Spearman, a pioneer in the field of factor analysis.

Career and Contributions

After completing his Ph.D., Cattell moved to the United States in 1937, where he began his career as a research professor at Columbia University. During his tenure at Columbia, he developed the 16 Personality Factors (16PF) questionnaire, a self-report personality test that is still widely used in psychology today.

Cattell's work in personality psychology extended beyond the 16PF. He is also known for his theory of fluid and crystallized intelligence, which he developed while working at the University of Illinois at Urbana-Champaign. According to Cattell, fluid intelligence is the ability to think logically and solve problems in novel situations, independent of acquired knowledge. Crystallized intelligence, on the other hand, is the ability to use skills, knowledge, and experience.

In addition to his work in personality and intelligence, Cattell made significant contributions to the field of multivariate statistics. He developed several statistical techniques, such as the scree test, to help in the analysis of multivariate data.

Later Life and Legacy

Cattell continued to work and publish extensively into his later years. He retired from the University of Illinois in 1973 but remained active in the field of psychology. He passed away on 2 February 1998 in Honolulu, Hawaii.

Cattell's contributions to psychology have left a lasting impact on the field. His theories on personality and intelligence continue to influence psychological research and practice. His statistical techniques have also found applications in various fields outside psychology, such as education, business, and social sciences.
