thermodynamicist (1897)
An 1897 encyclopedia definition of thermodynamicist, defined as a student of or one versed in thermodynamics. [7] In 1891, William Magie was described as a “thermodynamicist trained by Helmholtz”. (Ѻ)
In science, a thermodynamicist is a person who studies systems and processes from a thermodynamic point of view. The universe, for the thermodynamicist, defined as that which is accessible to experiment, is made up of the "system" examined and its "surroundings" able to act on its evolution. [1] To a good approximation, French engineer Sadi Carnot was the world's first thermodynamicist; followed by Emile Clapeyron, Hermann Helmholtz, William Thomson, Peter Tait, William Rankine, and Rudolf Clausius.

A closely related term to thermodynamicist, generally a post 1940s term, was "energeticist", a term of the late 19th century. American Willard Gibbs, for instance, was often referred to as an energeticist; whereas, in modern terms, he is considered a chemical thermodynamicist or more specifically the "founder of chemical thermodynamics". [2] In the 1890s, by comparison, German energeticist Wilhelm Ostwald, often considered as the founder of the "school of energetics", who had recently translated Gibbs' On the Equilibrium of Heterogeneous Substances into French, styled Gibbs as the "founder of chemical energetics". [3]

The following is a noted quote, that seems to have originated in originated with Percy Bridgman (1941), regarding how there is a different version of the first law and or second law for ever thermodynamicist: [4]

“There’s as many formulations of the second law as there have been discussions of it.”

This was rephrased by Clifford Truesdell (aware or not of the Bridgman-version) in 1969 as follows: [5]

“I hesitate to use the terms ‘first law’ and ‘second law’, because there are almost as many ‘first laws’ as there are thermodynamicists, and I have been told by these people for so many years that I disobey their laws that now I prefer to exult in my criminal status and non-condemning names to the concrete mathematical axioms I wish to use in my outlaw studies of heat and temperature. The term ‘entropy’ seems superfluous, also, since it suggest nothing to ordinary persons and only intense headaches to those who have studied thermodynamics but have not given in and joined the professionals.”

This has since come to be known as:

“There’s as many version of the second law as there are thermodynamicists.”

This last version, supposedly, began to be used in the 1950s. [6]
