Sadi Carnot

Sadi Carnot (Paris, June 1, 1796 - Paris, August 24, 1832) was a French mathematician who wrote on the principles of the second law of thermodynamics in his treatise on heat engines (Carnot cycle).

Sadi Carnot, a son of the eminent geometer Lazare Nicholas Marguerite Carnot, was the most eminent of Fourier's contemporaries who were interested in the theory of heat. Sadi Carnot was born at Paris, France, in 1796, and died there of cholera in 1832; he was an officer in the French army.

In 1824 he issued a short work entitled Réflexions sur la puissance motrice du feu, in which he attempted to determine in what way heat produced its mechanical effect. He made the mistake of assuming that heat was material, but his essay may be taken as initiating the modern theory of thermodynamics.
