 Nicolas Léonard Sadi Carnot

Nicolas Léonard Sadi Carnot (1796–1832) was a French physicist and engineer, often referred to as the "father of thermodynamics." He is best known for his seminal work on the principles of heat and work in mechanical systems, particularly through his formulation of the Carnot cycle. This idealized thermodynamic cycle helps to demonstrate the maximum possible efficiency of a heat engine operating between two temperatures.
