According to University of Texas at Austin psychology professor Karl M. Dallenbach, "Ogden was the first and principal proponent of Gestalt psychology in America." Similarly, in his review of Ogden's 1926 "Psychology and education", D. T. Howard, a professor of psychology at Northwestern University, called Ogden's use of Gestalt psychology "a pioneer work." As Dean, he invited German-born psychologists Kurt Koffka, Wolfgang Köhler, and Kurt Lewin to teach at Cornell.
