Ludwig Clamor Marquart

From Wikipedia, the free encyclopedia

Ludwig Clamor Marquart (March 29, 1804 – May 10, 1881) was a German pharmacist and entrepreneur who was a native of Osnabrück.

As a teenager he was a pharmacist’s apprentice in the town of Dissen, and afterwards an assistant pharmacist in Lingen and Werden. Later he was an overseer of pharmacies in the district of Cologne, and in 1835 received a doctorate in Pharmaceutical Chemistry from the University of Heidelberg. In 1837 he started a private pharmaceutical institute in Bonn, where he taught classes until 1845. One one his students at the institute was renowned chemist Remigius Fresenius (1818-1897).

In 1845 he founded Marquart's Lager chemischer Utensilien in Bonn, which was a factory that produced fine chemicals and pharmaceuticals. Today the operation in Bonn is part of Evonik; thus making it one of the oldest producers of chemicals in Germany.

Marquart is credited for coining the chemical term "anthocyanin" to describe a blue pigment derived from flowers.
