Friedrich Albrecht Carl Gren

From Wikipedia, the free encyclopedia

Friedrich Albrecht Carl Gren (May 1, 1760 - November 26, 1798) was a German chemist who was a native of Bernburg. He began his career working in a pharmacy in Bernburg, and later worked as a pharmacist in Offenbach am Main and Erfurt. In 1782 he began his studies at the University of Helmstedt, and in 1788 became professor of chemistry and physics at the University of Halle.

In 1790 Friedrich Gren was founder of the Journal der Physik, which in 1799 was renamed Annalen der Physik by Ludwig Wilhelm Gilbert (1769-1824). Today it is the oldest and one of the best-known journals on physics. He was also the author of a popular textbook on chemistry titled Systematisches Handbuch der gesamten Chemie.

Gren was a major proponent of the theory concerning the existence of phlogiston. After Antoine-Laurent Lavoisier demonstrated that combustion required oxygen, he compromised his beliefs, and postulated that oxygen and phlogiston worked alongside each other.
