About the author
Born in Painesville, Ohio, in 1842, George Trumbull Ladd studied at Western Reserve College and Andover Theological Seminary before beginning his career in the ministry. He later turned toward academic life, teaching at Bowdoin College and then at Yale, where he became one of the early figures to shape psychology as a university discipline in the United States.
Ladd is especially remembered for books that helped establish experimental psychology for American students, even though he saw psychology as closely tied to philosophy. His work ranged widely across psychology, metaphysics, ethics, and the philosophy of religion, and in 1893 he served as the second president of the American Psychological Association.
His influence was not limited to the United States. Yale’s archival record highlights his international travels and connections in East Asia, and reference works note the impact of his lectures and writing in Japan. He died in New Haven, Connecticut, in 1921, leaving behind a body of work that reflects both the scientific ambitions and the philosophical depth of psychology in its early years.
