Jöns Jacob Berzelius was a Swedish chemist. He worked out Berzelius, Father of Swedish Chemistry. 1779 - 1848 John Dalton, First Useful Atomic Theory.
He was a dominant figure in chemical science. Berzelius gave the oxygen arbitrary atomic mass 100 and referred all other atomic masses on the oxygen. Later he chose as a reference point and the hydrogen. Jöns Jakob Berzelius J. J.

Jons Jacob Berzelius (1779-1848), a Swedish chemist invented the chemical short cut used today. He was a professor of chemistry and pharmacy and this system of notations helped him to show the chemical composition easily to his medical students. about his atomic theory – and his symbols.
The atomic theory was taught by Bergman, Cullen, Black, &c., just as far as it was by Higgins. The latter, indeed, states some striking facts respecting the gases, and anticipated Gay-Lussac's theory of volumes ; but Mr. Dalton first generalized the doctrine, and thought of …
He is especially noted for his determination of atomic weights, the development of modern chemical symbols, his electrochemical theory, the discovery and isolation of several elements, the development of classical analytical techniques, and his investigation of isomerism and catalysis, phenomena that owe their names to him.

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. He discovered three chemical elements: cerium, thorium, and selenium, and devised the modern method by which one or two letters are used to symbolize the elements. The most notable of Berzelius's contributions to chemistry was his development of a rational system of atomic symbols. Around 1810 Berzelius was working to confirm John Dalton's atomic theory as well as Proust's law showing that separate elements always combined in whole-number proportions.
