Originally, it was generally believed that life was not subject to the laws of science the way non-life was. It was thought that only living beings could produce the molecules of life (from other, previously existing biomolecules). Then, in 1828, Friedrich Wohler published a paper on the synthesis of urea, proving that organic compounds can be created artificially. The dawn of biochemistry may have been the discovery of the first enzymes, diastase (today called amyalse), in 1833 by Anselme Payen. Eduard Buchner contributed the first demonstration of a complex biochemical process outside of a cell in 1896, alcoholic fermentation in cell extracts of yeast. Although the term biochemistry seems to have been first used in 1882, it is generally accempted that the formal coinage of biochemistry occurred in 1903 by Carl Neuberg, a German chemist.
