Abstract
George Gamow burst upon the European community of physicists like a meteor from outer space. The origin of his trajectory was distant Leningrad; his point of impact was Göttingen;. The time was mid-June 1928. The impression Gamow made has been recorded by Léon Rosenfeld. “I shall never forget,” Rosenfeld recalled, “the first time he appeared in Göttingen — how could anyone who has ever met Gamow forget his first meeting with him — a Slav giant, fair haired and speaking a very picturesque German; in fact he was picturesque in everything, even in his physics.”1 Gamow had learned German from a private tutor as a youth in Odessa with the result, he later recalled, that “I’m terribly poor inder,die,das, and my grammar is horrible, but pronunciation good.”2

Gamow, “Anomale Dispersion an den Linien der Hauptserie des Kaliums (Verhältnis der Dispersionskonstanten des roten und violetten Dubletts),”Zeit. f. Phys. 44 (1927): 887–892, took him completely by surprise when it appeared — Rogdestvenski had given the research to Prokofiew for completion without Gamow’s knowledge.

This expression for the decay constant, as Gregory Breit pointed out to Gamow and Houtermans by letter, contains a calculational error: the first two terms should be In (4πm/h) + 2 In v. The difference is unimportant, as it results only in slightly larger absolute values assumed for the radii r0. See R. Atkinson and F.G.

These letters are in the Bohr Scientific Correspondence (hereafter BSC) in the Archive for History of Quantum Physics (hereafter AHQP). There are copies of the AHQP in the A.I.P. Center for History of Physics, New York; the American Philosophical Society Library, Philadelphia; the Bohr Institute, Copenhagen; the University of California, Berkeley; the University of Minnesota, Minneapolis; the Accademia dei XL, Rome; the Science Museum, London; and the Deutsches Museum, Munich. By October 25, 1928, Bohr could write to Joffe extolling Gamow’s scientific gifts. Joffe actually did not receive this letter, so Bohr had to write him again on December 27 enclosing a copy of his earlier letter.

Condon’s article (note 55, pp. 321–322) makes it clear that Gurney–s textbook writing after the war was to a great degree necessitated by his inability to secure a security clearance and hence a stable position, for unknown political reasons.

See Bohr to Fowler, December 14, 1928, BSC, where Bohr proposes Gamow’s visit and also tells Fowler that Hartree and Mott will be able to describe Gamow’s plans and work personally. Also see Gamow’s My World Line (note 32), pp. 66–69, where Gamow claims that Bohr wrote to Rutherford directly. However, Gamow probably was mistaken about that, as there is no letter extant in the Rutherford correspondence from Bohr during the period in question.

G. Gamow, Constitution of Atomic Nuclei and Radioactivity (Oxford: Clarendon Press, 1931). The book is dedicated “To the Cavendish Laboratory, Cambridge” and the Preface was signed in Copenhagen on May 1, 1931. Gamow had been much concerned with the behavior of the nuclear electrons for years, but especially following O. Klein’s discovery of the so-called Klein paradox in Copenhagen at the end of 1928.
