Sadi Carnot

1 June 1796 – 24 August 1832

Nicolas Léonard Sadi Carnot (1796-1832) was a French military engineer and physicist often described as the 'father of thermodynamics'. His single published work, 'Reflections on the Motive Power of Fire' (1824), gave the first successful theory of the maximum efficiency of heat engines and introduced the idealized Carnot cycle.
