What is the setting of When Nietzsche Wept by Irvin D. Yalom?

The story is set mostly in Vienna in the year 1882. Medical research is thriving, and Dr. Breuer and Sigmund Freud are highly involved in the medical community. Nietzsche is not a member of the Viennese medical community. He has traveled to Vienna just to consult with Dr. Breuer. He is an outsider, not just in Vienna, but everywhere he goes.
