Robert Sessions Woodworth

Born in Belchertown, Massachusetts, Robert Sessions Woodworth (October 17, 1869 – July 4, 1962) became one of the major American psychologists of the early 20th century. He studied at Amherst College, continued at Harvard, and later earned his doctorate at Columbia University, where he built a long academic career.

Woodworth is especially remembered for his work in experimental psychology and for developing what he called dynamic psychology, an approach that emphasized how drives and motives help shape behavior. He also created the Woodworth Personal Data Sheet, an early personality screening test, and became known for trying to bring together ideas from different schools of psychology instead of sticking to a single camp.

Beyond his theories, he had a lasting impact through teaching and writing. His books, including Psychology: A Study of Mental Life and Experimental Psychology, were widely used for many years and helped introduce countless readers to the field in a clear, systematic way.
