George Nicholas Hatsopoulos (January 7, 1927 – September 20, 2018) was a

Greek American mechanical engineer noted for his work in thermodynamics and for having co-founded Thermo Electron
.

Early life

Hatsopoulos was born in Athens, Greece in 1927

Athens Polytechnic School, Nicolas Kitsikis. He attended Athens Polytechnic before entering MIT, where he received his Bachelor and Master of Science (1950), Mechanical Engineer (1954), and Doctorate of Science (1956).[2]

Personal life

Hatsopoulos-Keenan reformulation of thermodynamics

In 1965, he and Joseph Keenan published their textbook Principles of General Thermodynamics, which restates the second law of thermodynamics in terms of the existence of stable equilibrium states.[3] Their formulation of the second law of thermodynamics states that:

When an isolated system performs a process after the removal of a series of internal constraints, it will reach a unique state of equilibrium: this state of equilibrium is independent of the order in which the constraints are removed.

The Hatsopoulos-Keenan statement of the Second Law

entails the Clausius, Kelvin-Planck, and Carathéodory statements of the Second Law,[4] and has provided a basis to extend the traditional definition of entropy to the non-equilibrium domain. Hatsopoulus and Keenan maintained that it is unlikely to identify a satisfactory definition of heat without a prior statement of the second law.[5]

In 1976, Hatsopoulos also contributed to a formulation of a unified theory of mechanics and thermodynamics, arguably a precursor of the emerging field of quantum thermodynamics.[6]

Academic and industry leader

While at MIT, Hatsopoulos was head of the engineering division of

M.I.T.
.

Recognition

In 1961, Hatsopoulos received the Golden Plate Award of the

Heinz Award in Technology, the Economy and Employment.[11]

In 2011, along with Arvin Smith and John Hatsopoulos, he was awarded the 2011

Chemical Heritage Foundation.[12]

Hatsopoulos is also a recipient of The International Center in New York's Award of Excellence.[citation needed]

He died on September 20, 2018, at the age of 91.[13] His net worth was reported as US$481 million in 2017.[14]
