E.U. Condon's major contributions were in atomic and molecular physics and spectroscopy; his book with G.H. Shortley on The Theory of Atomic Spectra dominated the field of spectroscopy for half a century and remains an invaluable reference. He also played an important role in the institutions of American science. He served for many years as the editor of Reviews of Modern Physics, and with Hugh Odishaw he edited the still widely used Handbook of Physics. After World War II, Condon became director of the National Bureau of Standards (now NIST), and helped to make it one of the premier research laboratories in the physical sciences in the world. The Selected Scientific Papers reprint many of the most important contributions Condon made to atomic physics, quantum theory, nuclear physics, condensed-matter physics and other fields. The Selected Popular Writings contain articles he wrote on technical topics for such journals as "The American Journal of Physics, Science, and " "Nature," as well as reflections on education, UFO's, and other topics.

This 1984 book brings together 48 studies and essays written by physicists from around the world to mark the 90th birthday of Louis de Broglie and the 80th birthdays of Paul Dirac and Eugene Wigner. Publication under one cover of studies based on the discoveries of scientific personalities as diverse as those to whom this volume is dedicated serves at least one important purpose: it concretely reflects the rival pathways in quantum physics at the time of this book's publication. From one perspective, the papers contrast the strategies of a champion of the mathematical approach (Wigner) with those of a thinker who relied on physical intuition (de Broglie). From another, they compare the views of a defender (Wigner) and and opponent of the Copenhagen school (de Broglie), as well as those of an individual who helped to reconstruct the prevailing quantal paradigm, only later to advocate a return to causality (Dirac).
