World War II Medal of Honor Recipient. He posthumously received the award on March 10, 1946 from US Army Major General Leland S. Hobbs (presented to his father) at the Trinity Evangelical United Brethren Church in Grand Island, New York for his actions as a private first class with Company C, 325th Glider Infantry Regiment, 82nd Airborne Division, US Army, on June 9, 1946 near Manche, Normandy, France. He joined the US Army in November 1942 and after his training, he served in North Africa, Sicily, and Italy. He was then sent to England in preparation for the D-Day invasion of Normandy, France. On June 7, 1944, his glider landed behind enemy lines and soon came under attack. He was cut off from the rest of the battalion and despite himself coming under increased fire, he stood up and began to fire his weapon at the attacking Germans in an attempt to suppress their fire and relieve the battalion, and was killed in the process at the age of 22. He was also awarded the Bronze Star and Purple Heart. His Medal of Honor citation reads: "He was a member of Company C, 325th Glider Infantry, on 9 June 1944 advancing with the forward platoon to secure a bridgehead across the Merderet River at La Fière, France. At dawn the platoon had penetrated an outer line of machineguns and riflemen, but in so doing had become cut off from the rest of the company. Vastly superior forces began a decimation of the stricken unit and put in motion a flanking maneuver which would have completely exposed the American platoon in a shallow roadside ditch where it had taken cover. Detecting this danger, Pfc. DeGlopper volunteered to support his comrades by fire from his automatic rifle while they attempted a withdrawal through a break in a hedgerow 40 yards to the rear. Scorning a concentration of enemy automatic weapons and rifle fire, he walked from the ditch onto the road in full view of the Germans, and sprayed the hostile positions with assault fire. He was wounded, but he continued firing. Struck again, he started to fall; and yet his grim determination and valiant fighting spirit could not be broken. Kneeling in the roadway, weakened by his grievous wounds, he leveled his heavy weapon against the enemy and fired burst after burst until killed outright. He was successful in drawing the enemy action away from his fellow soldiers, who continued the fight from a more advantageous position and established the first bridgehead over the Merderet. In the area where he made his intrepid stand his comrades later found the ground strewn with dead Germans and many machineguns and automatic weapons which he had knocked out of action. Pfc. DeGlopper's gallant sacrifice and unflinching heroism while facing insurmountable odds were in great measure responsible for a highly important tactical victory in the Normandy Campaign."
