He had enlisted in the Army. Served during World War II. He had the rank of Sergeant. Service number was 32237155. Served with 36th Infantry Division, 143rd Infantry Regiment.
Arriving in the Remiremont area on 20 September the three 36th Division Regiments (141st, 142nd and 143rd) attacked the same night. Using a series of feints the 141st was able to cross the Moselle north of town and enlarge its bridgehead by the next afternoon. German determination and resistance was strong but the 142nd, in house-to-house fighting, forced the Germans to flee at daybreak on 23 September, destroying a bridge over the Moselle as they left. That same morning Platoons A-1, B-2 and C-1 engaged two ME-109s and shot one down. By then, large enemy reinforcements had begun to appear on the Division's right flank and the brilliant, rapid advance from the Southern France beachhead slowed considerably.
