Ted Stellmack was a member of the Military Police at Los Alamos. Stellmack graduated high school in June 1945 and was recruited by the Army soon thereafter. He was sent to Fort Sheridan, Illinois for evaluation and then assigned to the Military Police Detachment at Los Alamos.
In the following 20 months he pulled duty at every site on The Hill. The first few months were split between 24 hours on duty and 24 hours in training. The physical training took place in a large open area called Bradley Field, while arms training took place at the bottom of a canyon. His group became eligible for transfer and/or discharge when civilian security began to phase into Los Alamos in 1947. Stellmack was discharged through Fort Bliss, with the rank of S/Sgt.
