Arthur Julius Hacker was born in Albany on April 14, 1916. With a military entry date of January 5, 1944, he served in the United States Army as a combat surgeon with the 106th division. On December 16, 1944 at the Battle of the Bulge, along side many deaths and missing United States military, Arthur was captured by the German army as a Prisoner of War. Arthur remained at Stalag 4B as a POW for a month until his move to Stalag 9B. Exact dates on his release are not clear, but a letter to his mother dated May 6, 1945 states that he was “still behind barbed wire, the only difference is that we are now under American control.” Correspondence and telegraphs following this letter support his release into American hands. As a result of his meritorious service during the war, Arthur was awarded the Bronze Star, a Purple Heart and the Combat Medical Badge. His date of separation from the military was December 24, 1946. Prior to his military history, Arthur attended public elementary and high schools in Rensselaer.

A notice of separation from service explains that she was qualified as a medical technologist and worked as a laboratory technician. She attended the U.S Naval Training School in Bronx, NY and the U.S. Naval Hospital in San Diego, California. After this service, Marilynn matriculated at Simmons College in Boston for one semester but left to become Arthur’s wife.
