J. Sadger

Born in 1867, Isidor Sadger was an Austrian physician and one of the early figures associated with psychoanalysis in Vienna. He is often listed in older publications as J. Sadger or J. (Isidor) Sadger, and his work appeared during the period when Freud’s ideas were beginning to spread.

Sadger wrote on psychology, sexuality, and literary subjects, and several antiquarian and library records preserve his name on books and essays from the early psychoanalytic era. Because he appears under slightly different forms of his name, modern readers may encounter him in catalogs as J. Sadger, Isidor Sadger, or J. Isidor Isaak Sadger.

He died in 1942. Today, he is remembered less as a household name than as part of the first generation of psychoanalytic writers whose work helps map the movement’s early history.
