Josiah Willard Gibbs (1839-1903), the American physical chemist. His ideas, which founded chemical thermodynamics and statistical mechanics, were expressed in elegantly austere mathematical form, in lesser-known journals, so few chemists understood them. Nevertheless, they were still giving new insights a century after their first appearance. In the 1870's he derived the Gibbs phase rule which deals elegantly with hetero- geneous equilibria, and devised the concept known as the Gibbs function which enables prediction of the feasibility and direction of a hypothetical chemical change. His later research included work on chemical potential and surface adsorption.
