Hans Stammreich

Hans Stamm Empire ( * July 16, 1902 in Remscheid, † March 6, 1969 in São Paulo, Brazil) was a Brazilian chemist of German origin. Tribe kingdom was a pioneer of molecular spectroscopy and Raman spectroscopy.

Life

Germany to 1933

Tribe kingdom took off in 1920 graduated from high school in Remscheid and then studied chemistry, physics and physical chemistry in Heidelberg and Berlin. In 1924 he received his doctorate from the Technical University of Berlin.

From 1924 to 1927, assistant master Reich of Adolf Miethe in the laboratory for photochemistry at the Technical University Berlin, then senior assistant at E. Lehmann. In 1930 he became head of the section " Spectroscopy and Spectral Analysis " at the Technical University, and began his habilitation. On April 4, 1933 he " TU Berlin National Socialist Aktionskommittee " the university was prohibited from writing to continue to enter, because of the " suspicion that you are non-Aryans " (quote letter ).

Emigrant in Paris, Palestine and Iran from 1933 to 1940

Tribe kingdom went first to Paris, where he could work at the Sorbonne because of a recommendation of Albert Einstein at Langevin and Fabry. He stayed there initially until 1935. Besides his extensive scientific activities tribe kingdom had there among other contact with Albert Einstein, Arthur Koestler and Lion Feuchtwanger. In 1935, the couple went tribe kingdom because of a recommendation letter from Albert Einstein, first to Palestine, but went to Tehran, where stem Empire had received an invitation to build a science faculty at the University a short time later. Due to the poor working conditions in what was then Persia tribe kingdom in 1936 returned to Paris.

1940 received the master empire a visa for Brazil. While wife Charlotte could leave right after Brazil, Hans Stamm Empire was held in Casablanca, where he eventually succeeded under adventurous circumstances to escape to neutral Portugal, from where he was able to continue the journey to Brazil.

Activity in Brazil from 1940

Master Reich worked in a company for gas discharge lamps, but then got a call in 1945 to the newly established University of Sao Paulo, where in 1947 he took over a chair. He searched again soon in the field of spectroscopy, where he among other things, 1956 succeeded the first to produce Raman spectra with helium lamps.

Master Reich died on March 6, 1969 following a heart attack in São Paulo.
