ABSTRACT
The work of Max Wertheimer (1880-1943) is discussed as the first evidence of research within psychology employing Gestalt concepts. His research into the subject of apparent movement, a phenomenon Wertheimer called phi phenomenon, is discussed. Wertheimer further influenced the development of Gestalt psychology through his description of the concept of isomorphism, and his research leading to the development of the Gestalt Principles of Perceptual Organization.
