After the end of World War II, Father Odo founded the Central European Rehabilitation Association (CERA), with the aim of providing war-torn Central Europe with food, clothing, medicine, and other necessities. In 1949, after CERA had fulfilled its function and was dissolved, Father Odo returned to the abbey of St. Bartholomew in Germany. He left the monastery in 1952 because of a heart condition, returning to his family castle in Altshausen.
