1869–1962
A pioneering American psychologist, he helped shift the field toward studying motivation, behavior, and the whole person rather than simple stimulus-and-response formulas. His textbooks and ideas shaped generations of students in the early 20th century.

by Robert Sessions Woodworth
Born in 1869 and active through the major formative years of modern psychology, Robert Sessions Woodworth became one of the best-known American psychologists of his era. He taught at Columbia University and was widely recognized for helping build psychology as a rigorous academic discipline.
Woodworth is especially remembered for his work on dynamic psychology, an approach that emphasized drives, motives, and the active role of the organism in behavior. That focus offered an important counterweight to narrower mechanical accounts of human action and helped broaden how psychologists thought about mind and behavior.
He also had a lasting influence through teaching and writing. His textbooks were widely used, and his clear, systematic presentation of psychology helped introduce the subject to many students and readers during the first half of the 20th century.
