Pillsbury, University of Michigan; Howard C. Warren, Princeton University; Kurt Koffka, visiting professor, Cornell University; and Edward B. Titchener, Cornell University. The April 1925 meeting at Princeton University provided many American psychologists with their first opportunity to meet Kiffiler and Koffka, the leading Gestalt psychologists.
