It is not clear what your requirement is: actual understanding of thermodynamics (nobody does, just learn the equations); or the History of thermodynamics.
For the former, some scientific/math literacy is required. Eg: https://imechanica.org/files/An%20introduction%20to%20thermo...
For the history I have no clue: I am a pragmatic scientist and learn the current functioning models. (till they break).
