Josef Mattauch (1895-1976), German physicist. Mattauch worked on mass spectroscopy, using it to investigate isotopic abundances (examples are shown on the blackboard). One of the results of his work was the Mattauch isobar rule (1934). Another was Mattauch-Herzog geometry, which led to the design of a new type of spectroscope. Mattauch worked at both the Kaiser Wilhelm Institute for Chemistry and the Max Planck Institute for Chemistry. Photographed at the Max Planck Institut fur Chemie, Mainz, Germany, during the Conference on Nuclear Masses and their Determination (10-12 July 1956).
