Théophile De Donder


Théophile Ernest De Donder was a Belgian mathematician, physicist and chemist famous for his work in developing correlations between the Newtonian concept of chemical affinity and the Gibbsian concept of free energy.

Education

He received his doctorate in physics and mathematics from the Université Libre de Bruxelles in 1899, for a thesis entitled Sur la Théorie des Invariants Intégraux.

Career

He was professor between 1911 and 1942, at the Université Libre de Bruxelles. Initially he continued the work of Henri Poincaré and Élie Cartan. From 1914 on, he was influenced by the work of Albert Einstein and was an enthusiastic proponent of the theory of relativity. He gained significant reputation in 1923, when he developed his definition of chemical affinity. He pointed out a connection between the chemical affinity and the Gibbs free energy.
He is considered the father of thermodynamics of irreversible processes. De Donder's work was later developed further by his doctoral student Ilya Prigogine. De Donder was an associate and friend of Albert Einstein.
He was in 1927, one of the participants of the fifth Solvay Conference on Physics, that took place at the International Solvay Institute for Physics in Belgium. Additionally, De Donder attended the Solvay Conferences of 1924, 1930, and 1948.
