He was a professor at [[University of Marburg|Marburg]] and [[Leipzig University|Leipzig]]. Kolbe was the first to apply the term [[chemical synthesis|synthesis]] in a chemical context, and contributed to the philosophical demise of [[vitalism]] through synthesis of the [[organic chemical|organic substance]] acetic acid from [[carbon disulfide]], and also contributed to the development of [[structural theory]]. This was done via modifications to the idea of "radicals" and accurate prediction of the existence of secondary and tertiary alcohols, and to the emerging array of organic reactions through his [[Kolbe electrolysis]] of carboxylate salts, the [[Kolbe-Schmitt reaction]] in the preparation of [[aspirin]] and the [[Kolbe nitrile synthesis]]. After studies with [[Friedrich Wöhler|Wöhler]] and [[Robert Bunsen|Bunsen]], Kolbe was involved with the early internationalization of chemistry through work in London (with [[Edward Frankland|Frankland]]). He was elected to the Royal Swedish Academy of Sciences, and won the [[Royal Society of London]]'s Davy Medal in the year of his death. Despite these accomplishments and his training important members of the next generation of chemists (including [[Aleksandr Mikhailovich Zaitsev|Zaitsev]], [[Theodor Curtius|Curtius]], [[Ernst Otto Beckmann|Beckmann]], [[Carl Graebe|Graebe]], [[Vladimir Markovnikov|Markovnikov]], and others), Kolbe is best remembered for editing the [[:de:Journal für praktische Chemie|''Journal für Praktische Chemie'']] for more than a decade, in which his vituperative essays on [[August Kekulé|Kekulé]]'s structure of benzene, [[Jacobus Henricus van 't Hoff|van't Hoff]]'s theory on the origin of [[chirality]] and [[Adolf von Baeyer|Baeyer]]'s reforms of nomenclature were personally critical and linguistically violent. Kolbe died of a heart attack in [[Leipzig]] at age 66, six years after the death of his wife, Charlotte. ==Life== Kolbe was born in Elliehausen, near [[Göttingen]], [[Kingdom of Hanover]] (Germany) as the eldest son of a [[Protestant]] pastor. At the age of 13, he entered the Göttingen Gymnasium, residing at the home of one of the professors. He obtained the leaving certificate (the [[Abitur]]) six years later. He had become passionate about the study of [[chemistry]], matriculating at the [[University of Göttingen]] in the spring of 1838 in order to study with the famous chemist [[Friedrich Wöhler]].<ref name="Britannica bio">{{cite web |url=https://www.britannica.com/biography/Hermann-Kolbe |title=Hermann Kolbe – German chemist |author=Alan J. Rocke|access-date=28 July 2016}}</ref> In 1842, he became an assistant to [[Robert Bunsen]] at the [[University of Marburg|Philipps-Universität Marburg]]. He took his doctoral degree in 1843 at the same university. A new opportunity arose in 1845, when he became assistant to [[Lyon Playfair, 1st Baron Playfair|Lyon Playfair]] at the new ''Museum of Economic Geology'' in London and a close friend of [[Edward Frankland]]. From 1847, he was engaged in editing the ''Handwörterbuch der reinen und angewandten Chemie'' (''Dictionary of Pure and Applied Chemistry'') edited by [[Justus von Liebig]], [[Wöhler]], and [[Johann Christian Poggendorff]], and he also wrote an important textbook. In 1851, Kolbe succeeded Bunsen as professor of chemistry at Marburg and, in 1865, he was called to the [[Leipzig University|Universität Leipzig]]. In 1864, he was elected a foreign member of the [[Royal Swedish Academy of Sciences]].<ref>{{cite book|last=Rocke |first=Alan J. |title=The Quiet Revolution: Hermann Kolbe and the Science of Organic Chemistry |location=Berkeley |date=1993 |isbn=978-0-520-08110-9}}</ref> He was elected as a member of the [[American Philosophical Society]] in 1874.<ref>{{Cite web|title=APS Member History|url=https://search.amphilsoc.org/memhist/search?year=1874;smode=advanced;startDoc=1|access-date=5 May 2021|website=search.amphilsoc.org}}</ref> In 1853, he married Charlotte, the daughter of General-Major Wilhelm von Bardeleben. His wife died in 1876 after 23 years of happy marriage. They had four children. ==Work in chemical research== As late as the 1840s, and despite [[Wöhler synthesis|Friedrich Wöhler's synthesis of urea]] in 1828, some chemists still believed in the doctrine of [[vitalism]], according to which a special life-force was necessary to create "organic" (i.e., in its original meaning, biologically derived) compounds. Kolbe promoted the idea that [[organic compound]]s could be derived from substances clearly sourced from outside this "organic" context, directly or indirectly, by substitution processes. (Hence, while by modern definitions, he was converting one [[organic compound|organic molecule]] to another, by the parlance of his era, he was converting "inorganic"—''anorganisch''—substances into "organic" ones only thought accessible through vital processes.) He validated his theory by converting [[carbon disulfide|carbon disulfide (CS<sub>2</sub>)]] to [[acetic acid]] ({{Chem2|CH3COOH}}) in several steps (1843–45). Kolbe also introduced a modified idea of structural [[radical theory|radicals]], so contributing to the development of [[structural theory]]. A dramatic success came when his theoretical prediction of the existence of secondary and tertiary [[Alcohol (chemistry)|alcohol]]s was confirmed by the synthesis of the first of these classes of organic molecules. Kolbe was the first person to use the word [[chemical synthesis|synthesis]] in its present-day meaning,<ref>Kolbe wrote the word "synthesis" describing his project to transform carbon disulfide into acetic acid.

He was intolerant of what he regarded as loose speculation parading as theory, and sought through his writings to save his beloved science of chemistry from what he regarded as the scourge of modern structural theory.<ref name="Britannica bio" /> His rejection of structural chemistry, especially the theories of the structure of benzene by [[August Kekulé]], the theory of the [[asymmetric carbon atom]] by [[Jacobus Henricus van 't Hoff|J.H. van't Hoff]], and the reform of chemical nomenclature by [[Adolf von Baeyer]], was expressed in his vituperative articles in the ''Journal für Praktische Chemie''. Some translated quotes illustrate his manner of articulating the deep conflict between his interpretation of chemistry and that of the structural chemists: <blockquote>«''...Baeyer is an excellent experimentor, but he is only an empiricist, lacking sense and capability, and his interpretations of his experiments show particular deficiency in his familiarity with the principles of true science...»''<ref name="Britannica bio" /><ref>{{cite journal |title=Begründung meiner Urtheile über Ad.
