Richard Mollier

Richard Mollier nsIn thermodynamics, Richard Mollier (1863-1935) was a German theoretical physicist, part of the Dresden school of thermodynamics, notable for his experimental research in thermodynamics, particularly work evolving enthalpy-entropy diagrams, which have since come to be known as Mollier diagrams.

Mollier published treatises such as The Entropy of Heat (1895) and New Graphs for Technical Thermodynamics (1904).

English engineer Bryan Donkin’s 1898 book The Entropy Diagram, co-written with Jules Boulvin, gives a bibliography of treatises on entropy, listing 20 works, including those of Willard Gibbs (1873), Hermann Helmholtz (1884), Gustav Zeuner (1890), Richard Mollier (1893), among others. [1]

Dresden school
German physicist Gustav Zeuner, founder of the Dresden school, was succeeded at Dresden, in 1897, by Mollier as professor of mechanical engineering.

Mollier diagrams
At the 1923 Los Angeles Thermodynamics Conference, it was decided that any thermodynamic diagram having enthalpy as one of its coordinates should thereafter be called a "Mollier Diagram". [17]
