  Jöns Jakob Berzelius - Wikipedia, the free encyclopedia
Jöns Jakob Berzelius (August 20, 1779 - August 7, 1848) was a Swedish chemist, who invented modern chemical notation and is considered one of the fathers of modern chemistry (along with John Dalton and Antoine Lavoisier).
In 1810 the school became a part of Medico-Kirurgiska institutet, the predecessor to the Karolinska Institute, and Berzelius was appointed professor in chemistry and pharmacy.
Berzelius - his life and work was written by J. Erik Jorpes and published in 1966 and 1970 (originally in Swedish, first published in 1949).

 Assigned reading on Berzelius
Jons Jacob Berzelius was born at Vaversande, Ostergotland, in Sweden, in 1779.
Berzelius was greatly disenchanted with the inaccuracy and inadequacy of the methods of analysis in use in his day.
In his autobiography Berzelius notes, many times I had to repeat my analysis with different methods to find that method which was most certain to give the correct result', that is the result in accordance with the atomic theory.

Berzelius developed the radical theory of chemical combination, which holds that reactions occur as stable groups of atoms called radicals are exchanged between molecules.
He believed that salts are compounds of an acid and bases, and discovered that the anions in acids would be attracted to a positive electrode, whereas the cations in a base would be attracted to a negative electrode.
Berzelius did not believe in the Vitalism Theory, but instead in a regulative force which produced organization of tissues in an organism.
