Very scarce first separate printings of three important papers on radium by Ernest Rutherford, the "father of nuclear physics". – Author, Contents: New Zealand-born British nuclear physicist Ernest Rutherford (1871-1937) already had been awarded the Nobel Prize in Chemistry when he moved from McGill University in Montreal to Victoria University of Manchester. To be able to continue his research he was particularly keen to obtain larger quantities of radium. On the other hand in 1905 the Austrian government, then a major player in international efforts to explore radioactivity, had "set up a radium production plant, and two years later it embargoed all exports of uranium ore and products in an attempt to monopolise the market. This continued until about 1913, when other sources could be exploited, for example from Cornwall, Portugal and Colorado." (...) "Thus, when Rutherford moved to Manchester in 1907 Austria was the only place to obtain significant quantities of radium." (Todd) To promote research with the radium at hand the Austrian Academy of Science with the help of investor Karl Kupelwieser, the uncle of Ludwig Wittgenstein, had set up a »Radium-Kommission«, which in 1910 became the famous Vienna Institute for Radium Research (Institut für Radiumforschung). Thanks to his personal contacts to Austrian Chemist Otto Brill Rutherford could organise a considerable quantity of radium in early February 1908 and immediately started experiments to obtain emanation in his laboratory until May 1908. – The documented results of Rutherford's experiments then were first printed simultaneously in the English original as a journal issue (Phil. Mag., vol. 6), as well as in present German translation, this being the first separate printing. The first offprint of the English version was published in August 1908. According to Chadwick et al. the follow up paper from 1911 (»II. Die Umwandlungsgeschwindigkeit«) was first published in German translation first, as present separate printing by the Austrian Academy, as this is true for the 3rd paper of this lot (see enclosed). – ENCLOSED: Ernest Rutherford and Bertram B.
