When Nietzsche Wept is a 1992 novel by Irvin D. Yalom, Emeritus Professor of Psychiatry at Stanford University, an existentialist, and psychotherapist. The book takes place mostly in Vienna, Austria, in the late 19th century (during the year 1882, concretely), and relates a fictional meeting between the famous doctor Josef Breuer and the extraordinary philosopher Friedrich Nietzsche. The novel is an excellent review of the history of the philosophy and the psychoanalysis, and also of some of the main personalities of the last decades of the 19th century.
