Joachim F. Wohlwill (1928–1987)

This paper describes events and interactions among scholars from the Geography and Psychology Departments at Clark University during the late 1960s. These events and interactions led to the establishment of a vigorous, informal program of training and research on the environment and behavior. The paper also describes an on-going, long-term organismic-developmental, systems-oriented research program which is an outgrowth of that activity. Paradigmatic research on critical person-in-environment transitions and open problems and issues are discussed.
