This is the second of three volumes which together contain the complete range of Lord Rutherford’s scientific papers, incorporating in addition addresses, general lectures, letters to editors, accounts of his scientific work and personal recollections by friends and colleagues. Volume two, first published in 1963, includes the papers published by Rutherford when professor of Physics at Manchester, 1907 to 1919. While the work of his laboratory ranged over the whole field of radioactivity, he himself devoted much effort to questions concerning the nature and properties of the α particle. Consideration of the scattering of α particles led him to the second of his outstanding achievements, the conception of the nuclear structure of the atom, which opened up a new era in Physics. In each volume can be found photographs of Rutherford and his collaborators, multiple graphs, tables, diagrams and charts, and also pictures of the original apparatus which is of historic interest.

The two decades between the first and second world wars saw the emergence of nuclear physics as the dominant field of experimental and theoretical physics, owing to the work of an international cast of gifted physicists. Prominent among them were Ernest Rutherford, George Gamow, the husband and wife team of Frédéric and Irène Joliot-Curie, John Cockcroft and Ernest Walton, Gregory Breit and Eugene Wigner, Lise Meitner and Otto Robert Frisch, the brash Ernest Lawrence, the prodigious Enrico Fermi, and the incomparable Niels Bohr. Their experimental and theoretical work arose from a quest to understand nuclear phenomena; it was not motivated by a desire to find a practical application for nuclear energy. In this sense, these physicists lived in an 'Age of Innocence'. They did not, however, live in isolation. Their research reflected their idiosyncratic personalities; it was shaped by the physical and intellectual environments of the countries and institutions in which they worked. It was also buffeted by the political upheavals after the Great War: the punitive postwar treaties, the runaway inflation in Germany and Austria, the Great Depression, and the intellectual migration from Germany and later from Austria and Italy. Their pioneering experimental and theoretical achievements in the interwar period therefore are set within their personal, institutional, and political contexts. Both domains and their mutual influences are conveyed by quotations from autobiographies, biographies, recollections, interviews, correspondence, and other writings of physicists and historians.

Through new perspectives from a mix of original monographs, biographies, autobiographical memoirs, edited collections of essays and documentary sources, translations, classic reprints, and pictorial volumes, this series will document the individuals, ideas, institutions, and innovations that have created the modern chemcial sciences.
