Viggo Beutner Drewsen
Viggo Beutner Drewsen (born April 13, 1858 in Denmark , † May 18, 1930 in New York City ) was a Danish chemist.
Drewsen was the son of a paper manufacturer and, after graduating from high school in 1876, initially studied at the University of Oslo before he went on to study with Carl Remigius Fresenius in Wiesbaden, where he became his assistant. From 1879 he studied at the University of Munich with Adolf von Baeyer , where he received his doctorate in 1882. In his dissertation he dealt with the synthesis of 2- nitrocinnamic acid he had developed , which was required for the Baeyer indigo synthesis (via an indole derivative). A method of indigo synthesis named after both of them via nitrobenzaldehydes and acetone was also temporarily used industrially and made its name known. He was then the private assistant of Adolf von Baeyer, a teacher at the Polytechnic in Trondheim and from 1887 to 1893 chemist and research manager in the paper and cellulose factory in Bøhnsdalen. In 1893 he emigrated to the USA, spent a year at the Glens Falls cellulose factory in Fort Edward (New York), founded his own company in 1895 and headed research at the West Virginia Pulp and Paper Company in New York from 1910.
In his day, he was a leading scientist in cellulose production and held a total of 43 patents.
