Max Wertheimer was a pioneering Gestalt psychologist born in 1880 in Prague. He studied psychology and received his doctorate in 1905. From 1910-1914, he worked with Wolfgang Kohler and Kurt Koffka to develop the fundamental concepts of Gestalt theory through experiments testing their ideas. He later served as a professor of psychology in Frankfurt from 1929-1933 before immigrating to the United States in 1933. There, he joined the faculty at the New School for Social Research in New York City, where he remained for ten years until his death in 1943 working to complete his research on "productive thinking".
