Josiah Willard Gibbs (February 11, 1839 – April 28, 1903) was an American mathematical physicist who contributed much of the theoretical foundation for general and chemical thermodynamics. As a mathematician and physicist, he was an inventor of vector analysis. He was the first person in the United States of America to receive a PhD in engineering (Yale). He was one of the earliest theoretical physicists in America and perhaps one of the earliest theoretical chemists.
Gibbs introduced the important notion of the Gibbs free energy.
