Wilhelm Eschweiler (born 1 December 1860 in Euskirchen and died 21 March 1936) is a German chemist. He is a professor at the Polytechnic School of Hanover

Life
He passed the final examination (Obersekunda) at the Knickeberg Institute in Telgte and completed his pharmacy studies in Goch. He then visited the pharmacies of Düsseldorf, Frankfurt, Elberfeld, Wiesbaden, Metz and Hamburg and studied pharmacy at the University of Munich and passed the state examination in 1886.

A year later, he became Karl Kraut’s assistant at the Inorganic Institute of the TH of Hanover. Meanwhile, he obtained his doctorate in 1889 at the University of Rostock, which dealt with contributions to the knowledge of formaldehyde. In 1892 he became a private lecturer in analytical chemistry in Hanover, where he also taught food chemistry. In 1895, he received the title of professor, and in 1921, he became associate professor. From 1927 to 1929, he was senior assistant. From 1900 to 1934, he was a lecturer in analytical chemistry.

He studies mineral dyes, polythionic acids and is considered an expert in explosives and gunpowder. In the latter field, he was often active as an industry consultant and investigated, among other things, the accident at the Oppau nitrogen plant in Ludwigshafen-Oppau in 1921. Much of his research has been published in the theses, diplomas and dissertations of his students. One of his students was Fritz Strassmann.

The methylation of Eschweiler-Clarke bears his name and that of Hans Thacher Clarke. Eschweiler published work on this subject in 1905 and Clarke in 1933. Sometimes, therefore, it is known only as the Eschweiler method ,.
