Dr. Carr was Professor of Clinical Psychology in Psychiatry of the Westchester Division of New York Hospital-Cornell Medical Center. A reel-to-reel audiotape of an interview by Arthur Carr with the adult Little Hans, Herbert Graf, is an accretion to this collection. Hans was the first born (1903) of psychoanalyst Max Graf, who was one of Freud's closest disciples. Four and a half year old little Hans had a sexually oriented phobia that started after the birth of his sister. He was seen by Freud. Psychoanalysts hailed the story of little Hans as the first confirmation of Freud's theory of infantile sexuality obtained by direct observation of a child. It was also the first example of child analysis and the first control analysis on record.
