Ludwig Rousseau

from Wikipedia, the free encyclopedia

Georg Ludwig Claudius Rousseau (born September 24, 1724 in Bad Königshofen im Grabfeld , † January 24, 1794 in Ingolstadt ) was a German pharmacist, pharmacist and chemist. He was a professor of chemistry at the University of Ingolstadt .

His father was a doctor from Arlon and worked in Neustadt an der Saale . Rousseau completed his apprenticeship as a pharmacist in Kitzingen , Würzburg , Augsburg (court pharmacy), Munich and Passau and in 1748 became a temporary pharmacist in Ingolstadt. In 1751 he married the daughter of the pharmacist Johann Sebastian Cavallo and took over one of his two pharmacies in Ingolstadt (the lower pharmacy ). He became a citizen of Ingolstadt and received the pharmacy certificate from the medical faculty of the university there. In addition, he received lessons from the anatomy professor Leonhard Obermayer , with whom he became friends, and also continued his self-study in physics, philosophy and chemistry. In 1760 he became a demonstrator for chemistry and in the same year also a teacher for theoretical chemistry, but only received the title of professor in the Philosophical Faculty in 1773. In 1775 he moved to the medical faculty, from which he was temporarily removed, but was reinstated in 1776 following his objection to the elector. He also received a medical doctorate, making him a professor of medicine. In addition to chemistry, he also taught natural history from 1773 and pharmacy from 1776. He sold his pharmacy. Rousseau had also been on the Ingolstadt city council for some time. In 1778 he built a chemical laboratory for the university (arose from his own pharmacy laboratory). He was dean of the medical faculty four times and rector of the university in 1790, to which he bequeathed his chemical library when he died.

He taught chemistry based on the textbooks by Johann Christian Polycarp Erxleben and Hermann Boerhaave . He later put forward both the phlogiston theory according to Georg Ernst Stahl and the more recent conception of chemistry according to Antoine-Laurent Lavoisier , without clearly taking sides (but leaning towards Lavoisier).

He was a member of the Leopoldina and the Agricultural Academy in Burghausen.
