Roland Heinrich Scholl ( born September 30, 1865 in Zurich, † August 22 1945 in a hurry castle ) was a Swiss chemist.

Life

Scholl studied after graduating from high school in Zurich from 1883 Chemistry at the University of Würzburg and at the Federal Polytechnic in Zurich. From 1887 to 1893 he was an assistant in Zurich and received his doctorate in 1890 at the University of Basel. In Zurich he taught as a Privatdozent in 1893 and his habilitation in 1894 at the Polytechnic of Zurich, where he then worked as a lecturer.

At the Commercial Academy Zurich Scholl was a lecturer in Silo in 1895 and was also an adjunct professor of chemistry at the School of Veterinary Medicine. In 1896 he accepted a call to the University of Karlsruhe as a full professor. In 1907 he became a full professor of chemistry at the University of Graz. In 1914 he was drafted into military service, from which he was released in 1916. From 1916 to 1934 he was Professor of Organic Chemistry and Organic Chemistry and Technology at the Technical University Dresden. It was at this time also director of the Organic Chemistry Laboratory of the University and from 1921 Executive Board of the Chemical Department. He signed in November 1933, the commitment of the professors at German universities and colleges to Adolf Hitler.

Work

Scholl was considered by his colleagues as a thorough and critical person. Early in his career, he investigated the structure of the pop acid and refuted here the formulas presented by Friedrich August Kekulé von Stradonitz or other. As of 1903, Scholl operated more in the field of vat dyes, Indanthren and Flavanthren, among other things, he clarified the constitution of dyes. During the work on the production of the Flavanthrensynthese pyranthrone, the first nitrogen - and sulfur-free vat dye succeeded.

By addressing these fused ring systems Scholl proposed a nomenclature that allows a simple way to identify these ring systems. More than 100 publications featuring his resume.
