History of biochemistry
The history of biochemistry can be said to have started with the ancient Greeks who were interested in the composition and processes of life, although biochemistry as a specific scientific discipline has its beginning around the early 19th century. Some argued that the beginning of biochemistry may have been the discovery of the first enzyme, diastase (today called amylase), in 1833 by Anselme Payen, while others considered Eduard Buchner's first demonstration of a complex biochemical process alcoholic fermentation in cell-free extracts to be the birth of biochemistry. Some might also point to the influential work of Justus von Liebig from 1842, "Animal chemistry, or, Organic chemistry in its applications to physiology and pathology", which presented a chemical theory of metabolism, or even earlier to the 18th century studies on fermentation and respiration by Antoine Lavoisier.
Chemurgy
Chemurgy is a branch of applied chemistry that is concerned with preparing industrial products from agricultural raw materials. The word "chemurgy" was coined by chemist William J. Hale and first publicized in his 1934 book "The Farm Chemurgic", the concept was mildly well-developed by the early years of the 20th century. For example, a number of products, including brushes and motion picture film, were made from cellulose. Beginning in the 1920s, some prominent Americans began to advocate a more widespread link between farmers and industry. Among them were William J. Hale and agricultural journalist Wheeler McMillen.
