Baumé

Bau·mé \bō-mā\ , Antoine (1728–1804), French chemist. Baumé operated a pharmacy and dispensary and designed industrial and laboratory apparatus. In 1768 he designed a hydrometer with a scale having two fixed points (the density of distilled water and that of a salt solution of known concentration), thus enabling the production of properly calibrated instruments. The scale has been named after him, and his name serves as an adjective indicating relationship to or use of the scale.
