A few years later in 1938, he was able to set up an accounting office in the Urquhart Building in downtown Moscow. This lasted until 1942 when Jack joined the United States Navy. One of his earliest duty stations was in Bremerton, Washington. He served in both France and England in the Navy supply service. A Lieutenant Commander, he was honorably discharged in 1945. After his time in the military, Jack came back to Moscow and returned to his accounting business. In fact he was auditor for the University of Idaho's ASUI Funds for the 1946/1947 year.
