Be it the Swiss Nobel laureate Alfred Werner who founded coordination chemistry or German Nobel prize winner Carl Bosch who developed the Haber Bosch process for high pressure synthesis of ammonia, 19th century has had legendary chemists whose contributions have been magnanimous in the field. Check this segment and discover some of the most important and famous chemists of the 19th century In the early 19th century most chemists believed the products of a living organism were produced through the agency of a vital force present only in living plants and animals. These products could be converted into other products in the laboratory, but could not be created in the laboratory from their elements. This view known as vitalism received a serious blow from Wohler in 1828 when he synthesized urea by reacting silver cyanate with ammonium chloride. This however did not mean the end.
This opened a new research field in chemistry, and by the end of the 19th century, scientists were able to synthesize hundreds of organic compounds. The most important among them are mauve, magenta, and other synthetic dyes, as well as the widely used drug aspirin States in 1793. After the beginning of the 19th century, a significant number of druggists and apothecaries ex-panded into chemical manufacturing. As Haynes put it, The 'laboratory' of every apothecary shop was an em-bryo chemical manufacturing plant (4). The War of 1812, again cutting off English goods, greatly helped domestic industry.

In 1823, British entrepreneur James Muspratt started mass producing soda ash (needed for soap and glass) using a process developed by Nicolas Leblanc in 1790.

Chemistry is a branch of science that has been around for a long time. In fact, chemistry is known to date back to as far as the prehistoric times. Due to the amount of time chemistry takes up on the timeline, the science is split into four general chronological categories. The four categories are.
During the 19th century much attention was given to the study of heat properties of various objects. An idealised model that was considered was the Black Body, an object which absorbs all incident radiation and then re-emits all this energy again. We can think of the radiating energy as standing waves inside our blackbody cavity Sites of Chemistry in the 19th Century.

Although chemistry was developing rapidly, it was microscopy which was the fundamental tool of the nineteenth-century forensic scientist and which piqued Gross's interest.
