[Jung to Freud 1905: a report on Sabina Spielrein]

A recently discovered letter, dated September 25, 1905, proves that Jung's first attempt to get in contact with Freud had taken place earlier than it was assumed on the basis of their published correspondence. The letter contains a brief case history of Sabina Spielrein's disease. It was addressed to Freud and handed over to Sabina Spielrein's mother who intended to remove her daughter from Jung with whom the girl had fallen in love. However, the letter was never passed on to Freud.
