Frederick Clark was born on January 21, 1916 in Pittsburgh, Allegheny County, Pennsylvania. He enlisted in the U.S. Army on January 11, 1943 at Pittsburgh, Pennsylvania. Frederick served as a Private 1st Class in the 285th Field Artillery Observation Battalion in the United States Army during World War II. He was Killed in Action on December 17, 1944 at the age of 28 and is now buried in the Gettysburg National Cemetery, Gettysburg, Adams County, Pennsylvania, USA. He was one of the victims of Malmedy massacre when German SS soldiers of the 1st Panzer Division captured over 100 American soldiers at Baugnez Crossroads outside Malmedy, Belgium, on 17 December 1944 during the Battle of the Bulge and, under orders to take no prisoners, placed them in an open field and then machine gunned them. When the machine guns stopped, the SS went through the field where some victims were still alive and systematically finished them off with pistols at short range leaving 84 soldiers dead when they had finished. Fortunately, when the machine guns first started shooting, a number of soldiers ran and some managed to escape and tell the story of how the Germans had treated the others who had not survived.
