Abstract :
THE following chronology of selected events especially pertintent to the realization of the alchemists´ dream of the centuries is intended to present only a typical cross section of the manifold aspects of the war-stimulated nuclear research. Inevitably, in a brief report on so ramified a project, many important aspects of the famous Manhattan Project and its predecessor and related enterprises are not reported here. Continuing security regulations, too, still prevent discussion of some of the aspects which would be of especial interest to engineers.
