text: The Institute consisted of two departments: Mass Spectrometry and Nuclear Physics was Josef Mattauchs department, while Nuclear Chemistry was Strassmanns department.  Mattauch was appointed director of the institute. Mattauch developed tuberculosis, and, in his absence, Strassman became acting director in 1948. As of 1949, the Kaiser-Wilhelm Institute was renamed the Max Planck Institute for Chemistry, and moved from Tailfingen to Mainz, Germany.
  In 1950 Strassmann became the official director of the institute. After Mattauch returned to the institute in 1951, there was considerable conflict over the allocation of resources to their respective departments.
