Josef Schintlmeister

Josef Schintlmeister (16 June 1908, Radstadt – 14 August 1971, Hinterglemm) was an Austrian-German nuclear physicist and alpinist from Radstadt. During World War II, he worked on the German nuclear energy project, also known as the Uranium Club. After World War II, he was sent Russia to work on the Soviet atomic bomb project. After he returned to Vienna, he took positions in East Germany. He was a professor of physics at the Technische Hochschule Dresden as well holding a leading scientific position at the Rossendorf Central Institute for Nuclear Research.

Schintlmeister had his doctorate and had completed his Habilitation.

During World War II, Schintlmeister, Dozent für Experimentalphysik (Docent for Experimental Physics), worked at the II. Physikalisches Institut der Universität, Wien (Second Physics Institute of the University of Vienna), where Georg Stetter was the director. One of his colleagues there was Willibald Jentschke. The Institute did research on transuranic elements and measurement of nuclear constants, in collaboration with the Institut für Radiumforschung (Institute for Radium Research) of the Österreichischen Adademie der Wissenschaften (Austrian Academy of Sciences). This work was done under the German nuclear energy project, also known as the Uranverein (Uranium Club); see, for example, the publications cited below under Internal Reports.

In work completed in June 1940 and published in 1941, Schintlmeister had followed a line of reasoning similar to that of Carl Friedrich von Weizsäcker and Fritz Houtermans and had predicted the existence of the 94th element, plutonium. In two papers published in May 1941, Schintlmeister spelled out the implications of the 94th element in that it could be generated in a Uranmaschine (uranium machine, i.e., a nuclear reactor) and that it would be fissionable.
