They settled in Lima in 1948, where he served as mayor in the 1970's. The family moved to Dell when he bought the old Dell schoolhouse bell and found out the schoolhouse went with the bell. He and his wife Ruth achieved national fame by turning the old schoolhouse into Yesterdays Calf-A and Museum.
