Meitner had discovered, and he was acutely conscious that the fundamental research had been done in Germany. He wanted the rest of the world to know of the significance of the work at least as soon as the Nazi planners did. By rushing into print with Hahn's manuscript he was able to alert the world community of physicists. Rosbaud was in Oslo from August 26 to September 16, 1939, a few days before Frank Foley abandoned Berlin and transferred to Oslo. There he visited Victor Goldschmidt, a geologist who studied the properties of uranium and "super-uranium" (plutonium). In Oslo Rosbaud also met Odd Hassel, an old acquaintance. Goldschmidt and Rosbaud were friends and when the persecution of Jews in Germany intensified in 1935, Rosbaud helped Goldschmidt abandon Göttingen and return to Oslo. In late autumn 1939 Rosbaud again visited Oslo and urged Hassel to warn Norwegian authorities about a likely German invasion of Norway. During the German occupation of Norway, Rosbaud visited Oslo in German uniform and met Professor Tom Barth, who had connections with the resistance movement. Among the reports Rosbaud supplied to the British was that Germany was producing rockets (V2) and that the German project for a nuclear bomb was not successful. Rosbaud has also been connected to the "Oslo report", a detailed list of new German weapons systems, but this seems to have been the work of Hans Ferdinand Mayer, technical director at Siemens. Many of his reports were smuggled out of Germany by couriers working for the Norwegian intelligence organisation XU. Norwegians who were studying at technical schools in Germany, such as Sverre Bergh, linked up with Rosbaud and transported the intelligence to occupied Norway, and from there it was sent to neutral Sweden. One daring route involved a flight from Berlin to Oslo, with airport mechanics at each end helping to hide microfilms on the plane. Rosbaud supplied Moe Berg and Horace Calvert with a list of scientists in the Russian sector of Berlin when scientists were sought to join the victors after the war. Pergamon founder and editor After the war, Rosbaud took up residence in England. He worked for Butterworth-Springer, a company set up in response to a Scientific Advisory Board that included Alfred Egerton, Charles Galton Darwin, Edward Salisbury, and Alexander Fleming. When the Butterworth Company decided to pull out of the English/German liaison, Robert Maxwell acquired 75% while 25% rested
