Marcel Pourbaix was born on 16 September 1904 in Myshega (Aleksin District, Tula Oblast, Russia, 54°31′N 37°2′E / 54.517°N 37.033°E), where his father was a consultant on an engineering project. A brilliant chemist, he performed his most well known research at the University of Brussels, studying corrosion. His biggest achievement is the derivation of potential-pH, better known as “Pourbaix Diagrams”. Pourbaix Diagrams are thermodynamic charts constructed using the Nernst equation and visualize the relationship between possible phases of a system, bounded by lines representing the reactions that transport between them. They can be read much like a phase diagram.
In 1963, Pourbaix produced "Atlas of Electrochemical Equilibria", which contains potential-pH diagrams for all elements known at the time. Pourbaix and his collaborators began preparing the work in the early 1950s.
Marcel Pourbaix was not only a scientist, but also a skilled pianist.
Marcel Pourbaix was born in Myshega (Russia), where his father was a consultant on an engineering project. He studied in Brussels and graduated from the Faculty of Applied Sciences of the Université Libre de Bruxelles in 1927.
By 1938, he had devised the potential-pH diagrams for which he became famous. In 1939, just before the outbreak of World War II, he presented to the Faculty his doctoral dissertation, accompanied by a thesis entitled "Thermodynamics of Dilute Aqueous Solutions. Graphical Representation of the Role of pH and Potential."
