In 1953 I was inducted into the Army. Since I had studied physics at college and worked for a short time in private industry, I was assigned to the Enlisted Scientific and Professional Personnel (SPP) Program and sent to the Army Chemical Center, in Edgewood, Maryland. There were more than two thousand SPPs at the center when I arrived, many of them recent graduates. We lived in a dormitory, and at times it felt almost as if we were still at school. That is, for a while. My job was to design and develop instruments to assess the yield of nuclear devices. Much of my work was stimulating, but other people were less fortunate. One evening at Drago’s Pizza & Bar, a group of us decided to stave off boredom by organizing a physics seminar, with each of us presenting a paper in his area of expertise. We asked Colonel Delmar, the laboratory commander, for permission, and he granted it, provided the seminar wouldn’t interfere with our assigned duties.
