Paul Karl Maria Harteck (20 July 1902 – 22 January 1985) was a German physical chemist. In 1945 under Operation Epsilon in "the big sweep" throughout Germany, Harteck was arrested by the allied British and American Armed Forces for suspicion of aiding the Nazis in their nuclear weapons program and he was incarcerated at Farm Hall, an English house fitted with covert electronic listening devices, for six months.

Harteck studied chemistry at the University of Vienna and the Humboldt University of Berlin from 1921 to 1924. He received his doctorate at the latter under Max Bodenstein in 1926. From 1926 to 1928 he was Arnold Eucken’s teaching assistant at the University of Breslau.
From 1928 to 1933, Harteck was a staff scientist at the KWI für physikalische Chemie und Elektrochemie (KWIPC) (Kaiser Wilhelm Institute for Physical Chemistry and Elektrochemistry) located in Dahlem-Berlin, where he worked with Karl Friedrich Bonhoeffer on experiments on parahydrogen and orthohydrogen. While at the KWIPC, he completed his habilitation in 1931 at the Humboldt University of Berlin where he also supervised the dissertation of Karl-Hermann Geib who later developed the Girdler sulfide process.
In 1933, Harteck went to do research with Ernest Rutherford at the University of Cambridge. During this time, Rutherford was working on accelerator-driven nuclear fusion, and Hareck was credited in the 1934 paper on the topic.
Upon his return from England in 1934, he became an ordinarius professor and director of the physical chemistry department at the University of Hamburg. From 1937, he was an advisor to the Heereswaffenamt (HWA, Army Ordnance Office). In April 1939, along with his teaching assistant Wilhelm Groth, Harteck made contact with the Reichskriegsministerium (RKM, Reich Ministry of War) to alert them to the potential of military applications of nuclear chain reactions. From that year, his department as a whole did research for the HWA, with emphasis on uranium isotope separation. From 1940, with Hans Suess, his focus was on the use of heavy water as a neutron moderator. In 1941, his department constructed a conversion unit for Norsk Hydro for the catalytic production of heavy water. In 1942, especially with the help of Werner Heisenberg, Harteck circumvented an appointment in Russia. In February 1943, Harteck and his colleague Johannes Jensen suggested a new type of centrifugal isotope separation, which was adopted by the Anschütz Company. Under his supervision Wilhelm Groth conducted the last enrichment experiments with the ultracentrifuge in Celle, a small town 120 km south of Hamburg. In late spring 1945, Harteck was arrested by the allied British and American Armed Forces and incarcerated at Farm Hall for six months under Operation Epsilon. In 1946, upon his return from incarceration, he became director of the chemistry department at the University, a position he held until 1950.
In 1951, Harteck became a resident professor at the Rensselaer Polytechnic Institute in Troy, New York, where he taught until 1968. In 1937 and 1952, he was nominated for the Nobel Prize in Chemistry.
The following reports were published in Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics), an internal publication of the German Uranverein. The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics.
