Hermann Kolbe

Born 27 Sep 1818; died 25 Nov 1884 at age 66. Adolphe Wilhelm Hermann Kolbe was a German chemist who accomplished the first generally accepted synthesis of an organic compound from inorganic materials. While working on his doctorate he also succeeded in producing acetic acid from inorganic compounds, which according to the doctrines of vitalism was impossible. In 1859, he succeeded using phenol and carbon dioxide to produce salicylic acid, which led to the cheaper production of acetylsalicylic acid, or aspirin. The two reactions came to be called Kolbe's synthesis.
