unusual facts about François Massieu


François Massieu

François Jacques Dominique Massieu (1832-1896) was a French thermodynamics engineer noted for his two 1869 characteristic functions, each of which known as a Massieu function (the first of which sometimes called free entropy), as cited by American engineer Willard Gibbs in his 1876 On the Equilibrium of Heterogeneous Substances.


Athanase Dupré

Louis Victoire Athanase Dupré (1808–1869) was a French mathematician and physicist noted for his 1860s publications on the mechanical theory of heat (thermodynamics); work that was said to have inspired the publications of engineer Francois Massieu and his Massieu functions; which in turn inspired the work of American engineer Willard Gibbs and his fundamental equations.
