Friedrich Albrecht Carl Gren (1 May 1760 – 26 November 1798) was a German chemist and 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'' (in 1795-97 called ''Neues 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 in regards to the existence of phlogiston. After Antoine-Laurent Lavoisier (1743-1794) demonstrated that combustion required oxygen, he compromised his beliefs, and postulated that oxygen and phlogiston worked alongside each other. == Selected writings == * ''Betrachtungen über die Gärung'', (Reflections on fermentation), 1784 * ''Systematisches Handbuch der gesamten Chemie'', (Systematic textbook on all chemistry), 1787-1794, last edition- 1819 (1787-1790) (Digital edition ) / (1806-1807) (Digital edition ) by the University and State Library Düsseldorf * ''Grundriss der Naturlehre'', 1787, sixth edition- 1820 (Digital 5th edition from 1808 ) by the University and State Library Düsseldorf 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Friedrich Albrecht Carl Gren」の詳細全文を読む スポンサード リンク
