Clemence Williamson Halteman Jr. was born on December 21, 1920, in Butztown, Northampton County, Pennsylvania. He was the son of Clemence Williamson Halteman and Marjorie Beatrice "Margaret" Brensinger Halteman. He served in the 52nd Bomber Squadron, 29th Bomber Group, Very Heavy, as a Second Lieutenant and Aircraft Commander of B-29 Superfortress #42-63571 during World War II.

On the early morning of May 11, 1945, a Boeing B-29 Superfortress #42-63571, commanded by 2nd Lt. Clemence W. Halteman Jr., departed Guam on a Twentieth Air Force mission targeting the Kobe Industrial Area in Japan. Shortly after takeoff, the aircraft was involved in a catastrophic accident and crashed before reaching its destination. All eleven crew members were lost. Wartime records initially reported one crew member as killed and ten as missing; however, the missing airmen were subsequently presumed dead, and no survivors were ever found. While contemporary accounts reported that the precise cause of the accident was never publicly disclosed, surviving records do not provide a definitive explanation.

2Lt Halteman was killed in action and was the only member of the crew whose body was recovered. He is now buried in the National Memorial Cemetery of the Pacific, Honolulu, Honolulu County, Hawaii, USA.
