Talk of Kistenmaker Professor Kistenmaker didn't write down his talk at the cremation ceremony, but he spoke as he felt at the moment. He talked about when he was the director of the Institute of Atomic Masses which was just across the street of the Institute where my father was the director of, the Institute of Nuclear Physics. He recalled the time they shared with great physicists. There was never a moment of friction between them, they were always on speaking terms. Besides fellow scientists they also were friends and shared their dedication to freemasonry.
