Psychologist James McKeen Cattell founded The Psychological Corporation in New York in 1921. Cattell was a leading figure in psychology and was the president of the American Psychological Association, as well as founder and editor of Scientific Monthly and head of Columbia University’s psychology department. At age 60, when Columbia dismissed him because of his public opposition to the draft in World War I, Cattell decided to pursue his interest in publishing. He joined forces with two former graduate students, Robert Sessions Woodworth and Edward Lee Thorndike.
