Jean Nicod

Jean George Pierre Nicod (1893, France – 16 February 1924, Geneva, Switzerland) was a French philosopher and logician.

In his best known work, he showed that the classical propositional calculus could be derived from one axiom and one rule, both expressed using the Sheffer stroke. He also proposed the Nicod's axiom and developed Nicod's criterion.

Nicod died at the age of 31 from tuberculosis.

The Institut Jean Nicod (Paris) — a branch of the French Centre National de la Recherche Scientifique (CNRS) -- is research laboratory at the interface between philosophy, cognitive science, and the social sciences — was named in honour of Nicod's memory. Jean Nicod's name is also commemorated by the prestigious Jean Nicod Lectures, delivered annually in Paris by a leading philosopher of mind or philosophically oriented cognitive scientist, and published as a series by the MIT Press. The lecturer is awarded the Jean Nicod Prize by the CNRS.
