Constantin Piron

Constantin Piron (1932, Paris - 9 May 2012, Lausanne) was a Belgian physicist^[1] who worked for most of his career in Switzerland.^[2]

In 1963 Piron earned his doctor of science degree from the University of Lausanne under the direction of Ernst Stueckelberg and Josef-Maria Jauch with a thesis on quantum logic, "Axiomatique quantique". He developed Jauch's methods (called the Geneva approach) for the foundations of quantum mechanics.

Piron's theorem (1964)^[3] is a famous representation theorem for quantum lattices.^{[citation needed]}

He was appointed assistant professor in the physics department of the University of Geneva in 1969 and professor ordinarius in 1974. He retired in 2000.
