Dr. Seaborg and President Kennedy at the Atomic Energy Commission headquarters building in Germantown MD on February 16, 1961. Dr. Seaborg's comments on this photo: "I briefed President Kennedy on the fundamentals of atomic structure and nuclear structure. Here I am briefing him. I must say he was a pretty apt pupil. He seemed to understand pretty well what I was trying to tell him. In fact, he was a much better pupil than some of the other Presidents that I worked for in trying to understand these things."
