  Station Information - Jöns Jacob Berzelius
Jöns Jacob 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 discovering that the atomic weights were also not integer multiples of hydrogen's, Berzelius also disproved Prout's hypothesis that elements were built up from atoms of hydrogen.
In order to aid his experiments, he developed a system of chemical notation in which the elements were given simple written labels -- such as O for oxygen, or Fe for iron -- and proportions were noted with numbers.

Jöns Jakob Berzelius (1779—1848) was one of Humphry Davy's contemporaries and rivals.
Berzelius was born into a well-educated Swedish family, but he experienced a difficult childhood because first his father and then his mother died.
Berzelius also applied his organizing abilities to mineralogy, where he classified minerals by their chemical composition rather than by their crystalline type, as had previously been done.

Berzelius was born in Linköping in Östergötland in Sweden, where he attended the school today known as Katedralskolan.

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.

The major intellectual synthesis of Berzelius career was "dualism", a line of thinking that could be traced back to the original electrochemical investigations both he and Davy had made.

Berzelius was a brilliant laboratory experimenter and chemical theorist.
In 1819, Berzelius published his Essai sur la Theorie des Proportions Chimiques, in which he summarized his extensive studies of the chemical composition of nearly 2000 compounds and his measurements of the atomic weights of the elements, obtaining results that are remarkably accurate even by today's standards.
Berzelius was also the discoverer or co-discoverer of three elements: cerium, selenium, and thorium.

Wöhler loved joking, especially with his old teacher Berzelius, who tended to appreciate jokes better than Liebig or Dumas did.
An example is the cartoon he drew showing Berzelius in the editorial office ("Redactorium") of his Annual Reports on the Progress of Chemistry, which he produced from 1821 until his death in 1848, and which made him the period's ultimate chemical authority.

"As Boyle might be seen as a man stepping from the tradition of alchemy to that of applied chemistry, so too may Berzelius be seen as a man stepping from the tradition of Lavoisier into that of organic chemistry.
He moved from the hierachal duality of acids and salts proposed by Stahl and Lavoisier to his own duality which saw substances composed of the generic and specific and eventually to one of compounds being made up of positive and negative portions.

 J.J. Berzelius 1779 - 1848
The Swedish chemist J.J. Berzelius is regarded as the inventor of the first real filter paper.
At the suggestion of Berzelius, the development and manufacture of such paper was begun around 1815 at J.H. Munktell's paper mill at Grycksbo, similar production was later begun in England and Germany, but the "Swedish Filter Paper" retained its leading position, and its characteristics particularly its purity, set the standard for analytical filter papers.
The paper which was hand-made at the time of Berzelius, is still made at the same paper mill today, but now with the aid of modern paper making technology.
