History of the Inventory Designer: The Physikalisch-Technische Reichsanstalt (PTR), founded in 1887 as a scientific institution subordinated to the Reich Ministry of the Interior and from 1934 subordinated to the Reich Ministry of Science, Education and People's Education, was the result of years of efforts to establish a state organisation for experimental natural research and precision engineering. The execution of extensive scientific-physical investigations as well as the simultaneous practical implementation of the results in precision mechanics and technology allowed the PTR to quickly play an important role in basic research. This scientific institution was headed by its president and a board of trustees set up for technical supervision and consultation. Presidents of the PTR: Hermann von Helmholtz 1887-1892 Friedrich Kohlrausch 1895-1905 Emil Warburg 1905-1922 Walther Nernst 1922-1924 Friedrich Paschen 1924-1933 Johannes Stark 1933-1939 Abraham Esau 1939-1945 In 1923, the Reichs-anstalt für Maß und Gewicht, which had emerged from the Normaleichungskommission in 1919, was merged with the PTR. Over the years, constantly growing or more specialised areas of responsibility have led to changes in the structure of the department. In the presidential department, laboratories, main workshop, main library and administration were directly subordinated to the president. Division II: Electricity (from 1936: for electricity and magnetism) Division III: Heat and Pressure Division IV: Optics Division V: Atomic Physics and Physical Chemistry (from 1939) Division VI: Precision Mechanics and Acoustics (from 1939) After 1945, the tasks of the PTR were transferred to the Physikalisch-Technische Bundesanstalt (Braunschweig) and the Deutsche Amt für Maß und Gewicht (Berlin). Inventory description: In 1977 and 1981 files of the Physikalisch-Technische Reichsanstalt and the Normaleichungskommission (NEK) were transferred from the Office for Standardization and Metrology of the GDR to the Zentrale Staatsarchiv Potsdam. They were combined under the designation PTR to form a stock (R 1519). The files of Divisions III to VI of the PTR as well as the organisation and business operations of NEK have been handed down incompletely. The file fragments for sound, vibration and pressure measurements in torpedo and mine development and further development of precision measuring instruments for the 1936 Olympic Games (inventory R 105), which were previously stored in the Federal Archives in Koblenz, were assigned to inventory R 1519 in Berlin in 1996. Content characterisation: An important part of the science policy of the National Socialist state is documented in the existing documents on the management, organisation, planning and reporting of the PTR. Further focal points are processes relating to research and training issues, in particular in Divisions I Measurement and Weight and II Electricity and Magnetism. Also preserved are documents on the development and testing of a target time camera that was used during the 1936 Olympic Games in Berlin, as well as some files on torpedo and mine development between 1940 and 1944.
