In 1944 and 45 I was employed as an ordinanceman at the Naval Ordinance Test Station at China Lake, California. In 1945 Los Alamos didn’t have a firing site capable of firing a full scale Fat Man with dummy pit. In fact, the only large firing site at old Anchor Ranch could barely handle one lens, so they came to the Navy and asked us to build some firing sites.

As told by his brother, Alan Stewart:  William Stewart arrived in Lamy, NM on 20 March 1944. He was a T/3 under Kistiakowsky and Bainbridge. Aside from being able to recognize him as the GI at the top in the well-known picture of the test bomb being hoisted to the tower for the Trinity test, I have known very little of his time at Los Alamos. He was a very private person and never spoke of those days but he did attend most of the reunions at Los Alamos and drove there frequently.

My father, Edward C. Long, received his BS in Physics at U. of GA just before the war started. He reported for the draft and was sent instead to Oak Ridge. He worked at Y-12 as a Calutron supervisor. I recall stories about the young female operators having difficulties when the Calutron controllers aged - they were apparently very difficult to control, and since the women didn't really know what they were doing anyway, sometimes they stressed out and had to be taken out of the area.

My mother, Mary Elizabeth Barnes, earned a degree in Chemical Engineering from Auburn. During the war, she had worked in Michigan at a land mine factory, where she did quality control work. She was hired at Y-12 after the war, working in radiochemistry. She recalled that her boss was completely against women being in an engineering position, so he gave her the dirty jobs - climbing up the inside of stacks or wading in sludge to take samples.
