In thermodynamics, **Robert B. Evans** (c.1940-) is an American mechanical engineer, noted for his 1969 essergy theory, argued to be an umbrella replacement term for the various types of thermodynamic potentials. [1]

Education

Evans completed his PhD, thesis “A Proof that Essergy is the Only Consistent Measure of Potential Work”, at Dartmouth College, Hanover H. H. Thayer School of Engineering. In 1980, Evans was associated with the Georgia Institute of Technology, School of Mechanical Engineering.

Other

There also is a 1962 book *A Contribution to the Theory of Thermo-economics*, by a Robert B. Evans, which is puzzling, as this pre-dates the known Evans PhD by seven years? [3]
