Benoit Paul Emile Clapeyron (1799-1864), French engineer who developed a mathematical reformulation of Sadi Carnot's Carnot cycle. Clapeyron originally designed locomotives and bridges; however, after he was he was offered a chair at the École des Mineurs in St Étienne, France, Clapeyron turned his attention to the study of thermodynamics. He expressed Carnot's principle using a graphical pressure and volume representation as well as through algebraic expressions. Carnot's work was not well-known before Clapeyron's developments. Clapeyron also found a formula to describe the heat of vaporization of a liquid as a function of its temperature and volume change upon vaporization, called Clapeyron's equation.
