He graduated as a physician and worked as a doctor, but also had a keen interest in chemistry. Origins of Organic Chemistry •Swedish chemist Jons Jacob Berzelius Classified compounds in 2 categories 1)Organic-obtained from living organisms - most chemists believed organics could only be synthesized in living organisms thus the theory of “vitalism” 2)Inorganic-obtained from mineral sources (non-living). Berzelius is credited with the experimental substantiation of atomic theory and its development and introduction in chemistry. During the years 1810–1816, Berzelius used materials from analyses of oxides and provided new evidence for the law of multiple proportions. 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).

Jöns Jacob Berzelius (1779–1848), who studied medi-cine at Uppsala in Sweden and in 1807 was appointed professor in chemistry and pharmacy at the Karolinska Institute (1). His fundamental contribution to the in-frastructure of chemistry was his role in the establish-ment of chemical terminology. He introduced such Jöns Jakob Berzelius (1779–1848) was an accomplished experimenter in the field of electrochemistry. He was a contemporary and rival of Humphry Davy , another electrochemical pioneer, but unlike Davy, Berzelius was much more systematic: he was given to running programs of hundreds of experiments and then deriving organized generalizations from them.

He termed the name in 1806 as interest upon organic chemistry rose at that time. Baron Jöns Jacob Berzelius (Swedish: [jœns ˈjɑ̌ːkɔb bæˈʂěːlɪɵs]; by himself and his contemporaries named only Jacob Berzelius, 20 August 1779 – 7 August 1848) was a Swedish chemist. Berzelius is considered, along with Robert Boyle , John Dalton , and Antoine Lavoisier , to be one of the founders of modern chemistry . [3] Jöns Jacob Berzelius (1779-1848) was a Swedish scientist, considered one of the most important chemists of his time and known for being a methodical experimenter. The construction of the theory of electrochemical dualism, the creation of the first list of atomic weights of the elements and the invention of chemical symbols were his most important works. The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols.
Despite a lot of work, he found that his techniques of analysis gave him no clear insight into the structure or composition of organic molecules.

Swedish chemist who was a disciple of Dalton. He developed the concepts of the ion and ionic compounds. This theory made the idea of the O 2 molecule ridiculous, and helped bring about the rejection of Avogadro's Hypothesis.

Jöns Jacob Berzelius - Jöns Jacob Berzelius - Organic chemistry: 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. Berzelius was the first person to make the distinction between organic compounds (those containing carbon), and inorganic compounds.
