Johann Stobbe
Johann (Hans) Stobbe (born June 9, 1860 in Tiegenhof near Danzig, † August 3, 1938 in Leipzig ) was a German chemist.
Life
Stobbe, son of the businessman and brewery owner Adolph Stobbe (1835–1885), attended the citizens' school in Tiegenhof and the secondary school in Danzig and Elbing . After graduating from high school (1881), he first studied art history and then chemistry at the Ruprecht-Karls University in Heidelberg , the Ludwig Maximilians University in Munich , the Kaiser Wilhelms University of Strasbourg and the University of Leipzig . He was active in the Corps Rhenania Heidelberg (1882) and the Corps Suevia Munich (1883). With a thesis on John Wislicenus (whose assistant he was), he was in 1889 in Leipzig for Dr. phil.PhD. After his habilitation in 1894, he became a private lecturer , associate professor (1899) and in 1904 full professor for organic chemistry . In 1928 he retired . In November 1933, as emeritus, he signed the professors' commitment to Adolf Hitler at German universities and colleges .
Stobbe's importance lay in the field of organic chemistry, including resins and paints. For example, in 1909 he dealt with the polymerization of styrene . His publications on phototropic substances were considered groundbreaking (those are those that change color when exposed to light). Stobbe discovered the phenomenon in polyene dyes, which he synthesized first (and called fulgenic acids). In 1893 he discovered the Stobbe condensation, named after him, of ketones or aldehydes with succinic acid ester. On behalf of the Saxon Academy of Sciences , he was in charge of the editing of the biographical-literary concise dictionary for the history of the exact sciences (Poggendorff) . Three volumes were published before his death.
