what made sigmund freud revolutionary
Two figures dominated the early 20th-century history of Os and Cs: the French psychiatrist Pierre Janet and the Austrian psychiatrist Sigmund Freud. While Janet expanded on existing medical ideas, 1 Freud represented a significant break from the past, a paradigm shift. Freud interpreted Os and Cs symbolically. This can be seen in his interpretation of a young woman's compulsive bedtime ritual.
