Harry Schmidt (chemist)

from Wikipedia, the free encyclopedia

Harry Schmidt , actually Christoph Siegfried Harry Schmidt (born August 21, 1897 in Leipzig , † October 4, 1980 in Miltitz near Leipzig) was a German chemist .

Life

Schmidt was born as the son of the teacher Ernst Schmidt in 1897, attended the Petri-Realgymnasium in Leipzig and graduated from high school in 1917. He then did military service in the army on the Western Front . In 1919 he began studying chemistry in Leipzig , but after a short time moved to Dresden , where in 1921 he passed the preliminary diploma examination at the Technical University . Another change of study location led him to the Georg August University in Göttingen . There he was finally in 1924 with the work the influence of free oxygen on hydro-aromatic compounds as an academic student of Heinrich Vienna House doctorate .

Schmidt took up a job in the chemical industry, in the Miltitzer Scientific Laboratory of the Schimmel & Co. company in Miltitz , where he was authorized signatory from July 1, 1928 . After the Second World War, the company was nationalized and finally converted to VEB Chemische Werke Miltitz . Schmidt worked there until his age-related retirement in 1966, most recently as a department head.

research

Schmidt's research activities extended to natural substances ; odor-active terpene compounds were of particular interest to him . Schmidt published it in the series of reports by Schimmel & Co., Aktiengesellschaft, Miltitz near Leipzig, on essential oils, fragrances, etc. and in scientific periodicals. He mainly examined the constitution of the pinene , where he succeeded in correcting Otto Wallach's misinterpretations , pinocarvone and pinocarveole , sabinol , verbenol and citral .
