2nd Lt. Henry J. Koller was born on April 6, 1921, in Oak Park, Illinois, to Henry C. Koller and Anna Schneider-Koller. He was known as “Bud” to his family. With his two sisters, he grew up first in Oak Park and Elmhurst, Illinois, and later at 1113 Elgin Avenue in Forest Park, Illinois.
Henry attended Saint John Lutheran School, York High School in Elmhurst, and graduated from Proviso Township High School in Maywood, Illinois. After high school, he worked as a tool and die maker.
He was inducted into the U.S. Army Air Corps on October 23, 1942, and sent to officer candidate school. His army serial number was O&783196. He was trained at a number of bases and military schools. These included: Santa Ana Army Airfield, Santa Ana, California, Smyrna Army Airfield, Smyrna, Tennessee, Chicago, Illinois, Miami Army Airfield, Miami, Florida, Mount Pleasent, New York, Las Vegas, Army Airfield, Las Vegas, Nevada, Carlsbad Army Airfield, Carlsbad, Nevada, and finally Tonopah Army Airfield, Tonopah, Nevada. During his training, he qualified as a bombardier.
On September 8, 1944, during a nighttime high altitude bombing training mission, the B-24 Henry was a crew member on crashed. The army ruled that the cause of the crash was a result of the pilot and co-pilot not paying attention to the plane’s altitude while attempting to deal with a mechanical malfunction.
Caius Carpenter, who was the crew’s aerial gunner and the only survivor told the Central Nevada Museum and Historical Society what he remembered about the crash.
According to him, Lt. Moss started up the plane but told engineering he was not going to fly the plane because of oil pressure problems. A second plane was assigned to the crew. The plane took off, but Lt. Moss returned to the field and landed because of low oil pressure. The crew was assigned a third plane to fly.
Carpenter stated that as they boarded the plane, the co-pilot, Lt. Forest Carl said, “Since it’s our third plane, it should be the charm.” He replied, “It probably will charm our asses.” He also said another crew member said, “This one will probably kill us.”
The bomber took off and crashed about three miles from the base. According to Carpenter, shortly after takeoff, he heard a loud explosion and the plane shuttered. He lost his balance and was knocked out. When he awoke, he found himself pinned by wreckage. He saw debris and body parts all around him.
On September 14, 1944, 2nd Lt. Henry Koller was buried at Oakridge Cemetery in Hillside, Illinois, in Section 10, Lot 251, Grave 1.
