Hermann Kienitz finished high school in Breslau (now Wrocław/Poland) in
1933 and matriculated in physics and mathematics. After 4 semesters study, he
changed to chemistry at the Schlesische Friedrich-Wilhelms-Universität Breslau
(now University of Wrocław) and the TH Breslau (now TU Wrocław). He com-
pleted his PhD in 1938 at Breslau on complex halogen salts of three-valent rho-
dium. Between 1939 and 1940, Kienitz worked as assistant at the TH Breslau and
began his research for a habilitation on the structure and absorption spectra (UV
and VIS) of salts of metal complexes. The work was stopped by his conscription to
army service at the end of 1940. In 1942, he was obliged to work as scientific assis-
tant at the IG Farben plant Ludwigshafen to participate in the development of cata-
lysts for the dehydration of gaseous hydrocarbons. In 1944, he became employee of
the BASF AG and worked in the oil pyrolysis plant Heydebreck (now KǛdzierzyn/
Poland). As refugee, he found a position at the Martin-Luther-Universität Halle-
Wittenberg but returned to Ludwigshafen shortly before regions of eastern
Germany were handed over from USA to Soviet troops (for portrait see Fig.

central research of BASF), Kienitz turned to the application of physical and
