Photographic light exposure calculator used by US soldier

Walter Eugene Hunkler was born on February 8, 1915, in Washington, Illinois. He was the second of two children born to John and Bertha Geiger Hunkler. His parents were born in Switzerland and immigrated to the United States. John was a teamster and day laborer. Walter graduated from high school and became a bartender. He married and had a child, but later divorced. After the December 7, 1941, Japanese attack on Pearl Harbor, Germany declared war on the US and a few days later America entered World War II. On January 19, 1942, Walter was drafted into the US Army. Walter became a medical technician, assigned to a medical detachment, 160th Field Artillery Battalion, 45th Infantry Division, nicknamed the Thunderbird Division. In June 1943, the Division was deployed to Europe. Walter went into combat that July in Sicily, Italy. As the Division advanced through Italy and France, Walter participated in several campaigns: Anzio, Rome-Arno, Southern France, and Ardennes-Alsace-Battle of the Bulge. In spring 1945, the Division advanced into Germany. Walter’s unit was operating with the 157th Infantry when, on April 29, 1945, the 45th Infantry liberated Dachau concentration camp in Germany. They discovered over 30,000 survivors in the camp and 2,310 corpses on a train. Walter witnessed and photographed atrocities, the horrible camp conditions, and the surviving inmates. Following Germany’s May 7 surrender, the 45th Infantry was stationed near Dachau. Walter returned to the US in September 1945, and was honorably discharged as a Technician Fourth Grade in October. He was deployed overseas for 691 Days; 511 of them in combat. He received a Bronze Star for bravery for risking his own safety while tending to the wounded, as well as many battle stars for campaigns where his unit fought. Walter returned to Washington, Illinois, and worked for the Central Illinois Light Company. In October 1956, Walter married Roberta Leighton (1916 – 2007). Walter did not speak about his wartime experiences. Only once, in 1947, did he allow Roberta to see the photographs he took at Dachau before sealing them inside a storage container where they remained for over fifty years. Walter, 76, died on September 8, 1991, in Peoria, Illinois.

The light calculator was donated to the United States Holocaust Memorial Museum in 2000 by Roberta E. Hunkler, on behalf of the Estate of her husband, Walter E. Hunkler.
