Ludwig Gattermann (1860-1920). Born in Goslar, the son of a baker. He studied chemistry briefly at Leipzig and Heidelberg, before coming under the influence of Carl Liebermann (1842-1914) at the polytechnic (Gewerbe Akademie) in Berlin. He took his doctorate at Göttingen where he met Sandmeyer. He became Meyer's assistant and followed him to Heidelberg. He became Professor of Chemistry at the University of Freiburg im Breisgau in 1900, where he was succeeded by Hermann Staudinger (1881-1965). Gattermann's name is associated with the Gattermann reaction (1890), the Gattermann-Koch reaction (1897), the Gattermann aldehyde synthesis (1898) and the Gattermann-Stika pyridine synthesis (1916). He was very interested in aromatic acids, but also prepared various exotic inorganic compounds, notably the preparation of pure (and highly explosive) nitrogen trichloride. His famous textbook of practical organic chemistry was fondly known (or perhaps more accurately derided) as "Gattermanns Kochbuch".
