Carossa's mother, on the other hand, was a devoutly Catholic and quite sensitive person. The young couple had just settled in the south Bavarian resort town of Bad Tölz when Hans was born. They then lived in several Bavarian hamlets. These moves left a feeling of insecurity in the mind of their sensitive and introspective son. Although Hans had a younger sister, Stephanie, a close relationship with her is not evident. He attended the Volksschule in Pilsting, the Gymnasium in Landshut, and the Hochschule in Munich.
