The key compound m the synthesis of aspirin salicylic acid is prepared from phe nol by a process discovered m the nineteenth century by the German chemist Hermann Kolbe In the Kolbe synthesis also known as the Kolbe—Schmitt reaction, sodium phen oxide IS heated with carbon dioxide under pressure and the reaction mixture is subse quently acidified to yield salicylic acid... 

Peculiar reactions occur during the oxidation of organic acid anions. In 1843, M. Faraday found that a hydrocarbon is evolved during the electrolysis of acetate solutions. These reactions were studied in 1849 by Hermann Kolbe, who showed that the acetate ions during electrolysis condense with the evolution of COj that is, the reaction (in modem notation)... 

In 1877, Hermann Kolbe (of the University of Leipzig), one of the most eminent organic chemists of the time, criticized van t Hoffs publication on The Arrangements of Atoms in Space. as a childish fantasy. 

My emphasis. Quoted by Michael Keas, "The Structure and Philosophy of Group Research," 111 who also quotes a letter from Hofmann to Hermann Kolbe (from a collection at the Deutsches Museum), in which Hofmann says that the entire history [Geschichte] of the ammonia type was completed in six weeks. In Keas, "The Structure and Philosophy of Group Research," 114. 

Frankland provides an early link between London and Manchester chemistry and between British and Continental chemistry. He was the first professor of chemistry at Owens College, in 1851. He had studied with Lyon Playfair at the Royal School of Mines in London, where he became fast friends with the young German student Hermann Kolbe. Frankland went with Kolbe to...

The gradual adoption of stmctural theory occurred with remarkably little resistance, although conservative chemists took more time to come to the more modem theoretical view. Hermann Kolbe, for example, held to his theory of "rational constitution," although by the errd of the 1860s, the differences between Kolbe s view and stmctrrral theory had largely disappeared 64).
