Alfred Werner developed the basis for modern coordination chemistry and proposed the octahedral configuration of transition metal complexes

Vladimir Vernadsky
Paul Ehrlich is noted for his work in hematology and immunology, and coined the term chemotherapy

William Ramsay published several notable papers on the oxides of nitrogen and followed these up with the discovery of argon, helium, neon, krypton, and xenon

Hermann Emil Fischer his name can still be found in the names of many chemical reactions and concepts

Jacobus Henricus van 't Hoff accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron. This three-dimensional structure perfectly accounted for the isomers found in nature


Henry Louis Le Chatelier is most famous for Le Chatelier's principle, which is used by chemists to predict the effect of a change in conditions on a chemical equilibrium


Sir James Dewar discovered a process to produce liquid oxygen in industrial quantities, developed an insulating bottle, Dewar flask, still named after him, to study low temperature gas phenomena, and observed that cold charcoal could produce a vacuum


Johannes Diderik van der Waals was the first to realise the necessity of taking into account the volumes of molecules and the intermolecular forces (now generally called "van der Waals forces") in establishing the relationship between the pressure, volume and temperature of gases and liquids


Alexander Mitscherlich his most important work was in the field of processing wood to create cellulose

Dmitri Ivanovich Mendeleev was the creator of the Periodic Table of Elements
Angelo Mariani started marketing a wine called Vin Mariani which had been treated with coca leaves

Julius Lothar Meyer was contemporary and competitor of Dmitri Mendeleev to draw up the first periodic table of chemical elements. Some five years apart, both Mendeleev and Meyer worked with Robert Bunsen


Friedrich August KekulÚ von Stradonitz discovered the ring shape of the benzene molecule after dreaming of a snake seizing its own tail


Emil Erlenmeyer formulated the Erlenmeyer Rule: All alcohols in which the hydroxyl  group is attached directly to a double-bonded carbon atom become aldehydes or ketones


Louis Pasteur is known for his demonstration of the germ theory of disease and his development techniques of inoculation, most notably the first vaccine against rabies; he also made a major discovery in the field of chemistry, regarding asymmetric molecules and the polarization of light


Robert Wilhelm Bunsen perfected the burner that was named after him, invented by British chemist/physicist Michael Faraday, and worked on emission spectroscopy of heated elements
