The Swedish chemist Jöns Jacob Berzelius (1779-1848) was one of the first European scientists to accept John Dalton's atomic theory and to recognize the need for a new system of chemical symbols. He was a dominant figure in chemical science.

Jöns Jacob Berzelius, the son of a clergyman-schoolmaster, was born on Aug. 20, 1779, at Väversunda, Sweden. He studied for 6 years at the medical school at Uppsala and then studied chemistry at the Stockholm School of Surgery.
