Johann Böhm (20 January 1895 – 27 November 1952) was a German Bohemian chemist who focused on photochemistry and radiography.
[1] Böhm studied at the German Polytechnic University in Prague and then worked with Fritz Haber in Berlin where he re-designed and considerably improved the Weissenberg x-ray goniometer.
[2] In 1926 George de Hevesy, then a professor at the University of Freiburg, invited Böhm to co-operate with him on a series of experiments in spectrographic analysis.
After World War II Böhm was allowed to remain in the country and become again a citizen of Czechoslovakia because he had been active in the anti-Nazi movement supporting Czech scientists such as Jaroslav Heyrovský, but was not permitted to continue his academic career.
He worked in an industrial research institute in Rybitví (Výzkumný ústav organických syntéz).
