The community of psychiatrists and psychologists in early twentieth century Europe cultivated a strong interest in the phenomenologically informed accounts of human existence offered by Heidegger. The psychiatrists, Binswanger (1968) and Boss (1957/1963; 1970/1979), developed personal relationships with Heidegger, and while Heidegger ultimately rejected Binswanger’s work, Boss worked closely with him throughout his life in order to keep his own work on a sound phenomenological footing. This interest in phenomenologically informed psychological practice and theory continued into the latter half of the twentieth century with psychiatrists and psychologists such as Erwin Straus, Eugene Minkowski, Hubertus Tellenbach, and Rollo May.
