Rollo May (1909–1994), James Bugental (1915–2008), Irvin Yalom (1931– ) and others: The American contribution

Rollo May has played a unique role in the development, and particularly the popularisation, of existential psychotherapy by translating it into easily accessible concepts and methods. His editing of the book Existence (1958) in collaboration with Henri Ellenberger and Joseph Angel led to the introduction of such figures as Binswanger, Minkowski and Boss to the American psychotherapy scene. To this day, the book remains a classic in the existential psychotherapy literature.
