Ernst Otto Beckmann (1853-1923).
Born in Solingen, he began his career as an pharmacist's assistant in Arolsen, Burg (Wupper), Leipzig and Cologne. After working for Fresenius in Wiesbaden, Beckmann studied chemistry and pharmacy at Leipzig. He taught pharmacy and chemistry at the Technische Hochschule in Brunswick, before moving back to Leipzig as an assistant to Wislicenus. He was briefly a Professor of Physical Chemistry at Leipzig and Giessen in turn before moving to Erlangen. He then became Director of the Laboratory of Applied Chemistry at Leipzig, and finally, Director of the new Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry in Berlin-Dahlem. His name is associated with the Beckmann thermometer, used to measure freezing and boiling point depressions, and the Beckmann rearrangement of oximes to amides. He was also interested in the analysis of foodstuffs and the chemistry of camphor.
