Lavoisier

 [lah-vwah-zya´]
Antoine Laurent (1743–1794). French chemist, born in Paris and later guillotined by the French Revolutionists. Lavoisier demolished the phlogiston theory (a theory of combustion) and explained the true nature of respiration by his introduction of quantitative relations in chemistry. He was secretary and treasurer of a committee seeking the uniformity of weights and measures in France, which led to the establishment of the metric system.
