In his Lectures on Animal Chemistry [the present work], published during the years 1806–8, he expounds his conception of life-phenomena in general and, besides, records a number of fresh facts in the sphere of organic analysis, which he later still further augmented” (Nordenskiöld, The history of biology, pp. 371–372, from a long account of this book).

Jacob Berzelius was one of the founders of modern chemistry. He was the first person to measure accurate atomic weights for the elements, which helped to confirm Dalton's Atomic Theory and was the basis of Mendeleev's periodic table.
His commitment to pure research science was evidenced by his view that few discoveries would be made if science were only seen as a means to an end. 2017-12-01 · Jöns Jakob Berzelius. An avid and methodical experimenter, Jöns Jakob Berzelius (1779–1848) conducted pioneering experiments in electrochemistry and established the law of constant proportions, which states that the elements in inorganic substances are bound together in definite proportions by weight. He is considered one of the founders of modern Organic chemistry was first defined as a branch of modern science in the early 1800's by Jon Jacob Berzelius. He classified chemical compounds into two main groups: organic if they originated in living or once-living matter and inorganic if they came from "mineral" or non-living matter. Like most chemists of his era, Berzelius believed in Berzelius was the first person to show the difference between organic compounds (those made with carbon), and inorganic compounds. He helped Gerhardus Johannes Mulder in his analysis of organic compounds such as coffee , tea and many proteins .
•Historically, the development of the periodic table was based on the classification of elements according to their chemical and physical properties.

Organic chemistry also posed problems in the discrimination between substances. Berzelius originally devoted his career to physiological chemistry, a field based upon the application of chemistry and physiology to substances derived from animals and plants. To that end, he mastered traditional extractive analysis and published papers on these analyses between 1806 and 1808 that became highly regarded by his peers. Baron Jöns Jacob Berzelius was a Swedish chemist.
Up through the early 19th century, naturalists and scientists observed critical differences between compounds that were derived from living things and those that were not. Berzelius embarked on a systematic program to try to make accurate and precise quantitative measurements and insure the purity of chemicals.
