The four speakers at the Niels Bohr Memorial Session of the American Physical Society's spring meeting in Washington, John A. Wheeler, Léon Rosenfeld, J. Rud Nielsen, and Felix Bloch, are shown with Aage Bohr, director of the Institute for Theoretical Physics in Copenhagen (whose remarks at the session honoring his father's memory are reproduced below), and with the president of the Society, John H. Williams of the University of Minnesota, who was chairman of the session.

On November 23, 1962, five days after the death of Niels Bohr, a ceremony to honor his memory was held at CERN, the international laboratory located near Geneva, Switzerland, which Professor Bohr had aided materially in creating a decade ago. This tribute was presented at the CERN memorial session by V. F. Weisskopf, professor of physics at the Massachusetts Institute of Technology, who has been on leave of absence for the past two years while serving as director general of CERN. Professor Weisskopf has recently agreed to continue at CERN in that capacity for an additional one‐year term—until August of next year.
