Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

"Rat Man" was the nickname given by Sigmund Freud to a patient whose "case history" was published as Bemerkungen über einen Fall von Zwangsneurose ["Notes Upon a Case of Obsessional Neurosis"] (1909). This was the second of six case histories that Freud published and the first in which he claimed that the patient had been cured by psychoanalysis.
