Peter Adolf Thiessen (6 April 1899 to 5 March 1990) was a German physical chemist.

He voluntarily joined the Soviet Union at the end of World War II, and he was rewarded with both Soviet medals and the Stalin Prize for his contributions to the Soviet Union's atomic bomb program.

Education

Thiessen was born in Schweidnitz (modern widnica, Poland).

He attended Breslau University, Albert Ludwigs University of Freiburg, University of Greifswald, University of Greifswald, and University of Göttingen from 1919 to 1923. He earned his doctorate in 1923 at Göttingen under Richard Adolf Zsigmondy.

Career

Thiessen was a supernumerary assistant at the University of Göttingen in 1923, and from 1924 to 1930, he was a regular teaching assistant. In 1925, he joined the Nationalsozialistische Arbeiterpartei (Nazi Party). In 1926, he became a Privatdozent at Göttingen. He became the head of an inorganic chemistry department in 1930, and in 1932 he became an untenured extraordinarius scholar.

Thiessen joined the Kaiser-Wilhelm Institut für Physikalische Chemie und Elektrochemie (KWIPC) of the Kaiser-Wilhelm Gesellschaft in 1933. (KWIPC) is a website that publishes articles about Thiessen's career (KWIPC). He became an ordinarius professor of chemistry at the University of Münster for a short time in 1935. He became an ordinarius professor at the Humboldt University of Berlin and the head of the KWIPC in Berlin-Dahlem later this year. He turned the KWIPC into a model National Socialism group as its head.

Rudolf Mentzel, who was head of the Reichsforschungsrat's chemistry and organic materials group, was the main advisor and confidant. (RFR, Reich Research Council). Thiessen, the KWIPC's director, had a Faradayweg in Dahlem that the former director Fritz Haber used for business purposes; Thiessen shared this apartment with Mentzel.

Thiessen had Communist contacts before the war ended. Manfred von Ardenne, the director of his private laboratory Forschungslaboratoriums for Elektronenphysik, and Nobel Laureate and director of the second research laboratory at Siemens, as well as Max Volmer, ordinarius professor and professor of the Berlin Technische Hochschule, had agreed to work together. The pact was a promise that whoever first made contact with the Soviets would speak for the remainder. The pact's threefold: (1) prevent plunder of their universities, (2) continue their work with little interruption, and (3) shield themselves from being sued for any political offences of the past. Thiessen, a leading Soviet chemist, arrived at von Ardenne's Institute on April 27, 1945, carrying a major of the Soviet Army. Both four of them were taken to the Soviet Union. In Sinop, a suburb of Sukhumi, Von Ardenne was made head of Institute A. Hertz was appointed head of Institute G in Athy, about ten kilometers southeast of Sukhumi and a suburb of Gul'rips (Gul'rips). Volmer transferred to the Nauchno-Issledovatel's Institute-9 (NII-9, Scientific Research Institute No. 1) (9) in Moscow; he had been given a design bureau to work on heavy water production. Thiessen, a professor at MIT, became a pioneer in the development of porous barriers for isotope separation.

Six German scientists, including Hertz, Thiessen, and Barwich, were called in for study at Sverdlovsk-44, which was responsible for uranium enrichment. The plant, which was smaller than the American Oak Ridge gaseous diffusion plant, was only worth less than half of the predicted 90% or higher enrichment.

After the successful examination of a bomb with uranium, uranium was awarded in 1951; the first test was conducted with plutonium. In first class, Thiessen received a Stalin Prize.

Thiessen, a Fellow of the Academy of Sciences, and from 1956 to East Berlin's Institute of Physical Chemistry. He served as chairman of the Forschungsrat der DDR from 1957 to 1965 (Research Council of the German Democratic Republic).

In 1990, he died in Berlin.
