Question: What job did both Ilse Rosenthal-Schneider and Max Planck have in common?
Context: The Max Planck Institute for Physics and Astrophysics is a former institute of the Max Planck Society in Germany.  Located in Garching near Munich, it was home to scientists such as Werner Heisenberg.  The institute was founded in 1958 as a successor to the Max Planck Institute for Physics in Göttingen.  In 1991, it was split into two successor institutes, the current Max Planck Institute for Physics and Max Planck Institute for Astrophysics, both located in Garching. Max Karl Ernst Ludwig Planck, FRS ( ; 23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918. The Max Planck Institute for Cell Biology was located in Ladenburg, Germany.  It was founded 1947 as Max Planck Institute for Oceanic biology in Wilhelmshaven, after renaming in 1968, it was moved to Ladenburg 1977.  It was closed 1 July 2003.  It was one of 80 institutes in the Max Planck Society (Max Planck Gesellschaft). Ilse Rosenthal-Schneider (April 25, 1891 – February 6, 1990) was a German-Australian physicist and philosopher.  She is best known for her collaboration and correspondence with physicists Albert Einstein, Max von Laue, and Max Planck.  Rosenthal-Schneider earned a PhD in philosophy in 1920 at the University of Berlin, where she first met Albert Einstein.  After leaving Nazi Germany and emigrating to Australia in 1938, she became a tutor in the German department at the University of Sydney in 1945 and taught history and philosophy of science.  In the 1940s and 1950s, she exchanged a series of letters with Albert Einstein about philosophical aspects of physics, such as theory of relativity, fundamental constants and physical reality.  She remained in contact with Einstein through correspondence until the death of Einstein in 1955. The Max Planck Institute for Solid State Research (German: "Max-Planck-Institut für Festkörperforschung") was founded in 1969 and is one of the 82 Max Planck Institutes of the Max Planck Society.  It is located on a campus in Stuttgart, together with the Max Planck Institute for Intelligent Systems. The Max Planck Institute of Neurobiology is a research institute of the Max Planck Society located in Martinsried, a suburb of Munich in Germany.  Research centers on the basic mechanisms and functions of the developing and adult nervous system.  Main focus areas include the mechanisms of information processing and storage.  It is one of 80 institutes in the Max Planck Society (Max Planck Gesellschaft). The Max Planck Institute of Biochemistry is a research institute of the Max Planck Society located in Martinsried, a suburb of Munich.  The Institute was "founded in 1973 by the merger of three formerly independent institutes: the Max Planck Institute of Biochemistry, the Max Planck Institute of Protein and Leather Research (founded 1954 in Regensburg), and the Max Planck Institute of Cell Chemistry (founded 1956 in Munich)." The Max Planck Institute for Marine Microbiology is located in Bremen, Germany.  It was founded in 1992, almost a year after the foundation of its sister institute, the Max Planck Institute for Terrestrial Microbiology at Marburg.  In 1996, the institute moved into new buildings at the campus of the University of Bremen.  It is one of 80 institute in the Max Planck Society (Max Planck Gesellschaft). The Max Planck Institute for Psycholinguistics (German: "Max-Planck-Institut für Psycholinguistik"; Dutch: "Max Planck Instituut voor Psycholinguïstiek") is a research institute situated on the campus of Radboud University Nijmegen located in Nijmegen, Gelderland, the Netherlands.  Founded in 1980, it is the only institution in the world entirely dedicated to psycholinguistics, and is also one of only three among a total of 90 within the Max Planck Society to be located outside Germany.  The Nijmegen-based institute currently occupies 5th position in the Ranking Web of World Research Centers among all Max Planck institutes (5th by size, 1st by visibility).  It currently employs about 135 people. The Max Planck Institute of Microstructure Physics at Halle is a research institute in Germany in the field of material research.  It was founded in 1992 as a follow up of the Academy of Science Institute of Solid State Physics and Electron Microscopy and moved into the new buildings between 1997 and 1999.  It is one of 80 institutes in the Max Planck Society (Max Planck Gesellschaft).
