Bergman

Bergman
made great contributions to the field of inorganic chemistry. He founded
current method of quantitative inorganic analysis, specifically for determining
Ca, Pb, and sulfuric acid. He introduced the
binomial nomenclature system for salts and drew up comprehensive tables of
chemical affinities. In addition to his chemistry, Bergman made contributions
in the fields of physics and geology, being the first person to classify
rocks based on the chemical composition. |

No portrait found |
Johan Afzelius, a Swedish chemist followed Bergman’s research
and continued to develop methods of quantitative analysis of
inorganic compounds (e.g., barium
selenite) and he is notable for having isolated formic acid from ants and
showed it was different from acetic acid. He also studied the chemistry of
nickel and oxalic acid. |

Jons Jacob Berzelius
|
|
Berzelius performed more than 2000 experiments
over a ten-year period to determine accurate atomic masses for the 50
elements then known. Besides his table of atomic weights, Berzelius
also discovered the elements cerium, thorium, selenium, and silicon. Berzelius made many other major contributions to
chemistry, The most important of these was the invention of a simple set of
symbols for the elements along with a system for writing the formulas of
compounds to replace the awkward symbolic representations of the alchemists |

Heinrich Limpricht 1827-1909
|
|
Limprict was one of the early organic chemists who
studied a wide range of organic compounds ranging from amino acids to
chlorine substituted aromatics to pyrrole. He
developed many new syntheses for aliphatic acids, alcohols, and aldehydes. Included in his accomplishments are the
syntheses of anthracene and diphenylacetylene. |

Wilhelm
R. Fittig
|
|
In addition to jointly
discovering the Wurtz-Fittig reaction for synthesis
of alkylbenzenes, Fittig
discovered a large number of organic compounds such as pinacol
and biphenyl. He identified and synthesized the first lactones, isolated phenanthrene from tar and did in depth investigations
into the structures of naphthalene and fluorene. |

Ira
Remsen
|
|
Remsen is known for defining rules governing the oxidation of
aromatic side chains and the protective effect of ortho
substituents. He also was the first to synthesize saccharin and attempted the
first reaction that tried to prove the existence of a reactive intermediate
by a trapping experiment. He also wrote several influential organic chemistry
textbooks. Ira Remsen's reputation as a chemist prompted his
appointment as one of the five original professors of |
