Jean Cavaillès (

French philosopher and logician who specialized in philosophy of mathematics and philosophy of science. He took part in the French Resistance within the Libération movement and was arrested by the Gestapo
on 17 February 1944 and shot on 4 April 1944.

Early life and education

Cavaillès was born in

maître de conférences in Logic and in General Philosophy at the University of Strasbourg
.

World War II

After the outbreak of World War II, he was mobilized in 1939 as an infantry lieutenant with the 43rd Regiment and was later attached to the Staff of the 4th

Colonial Division. He was honoured for bravery twice and was captured on 11 June 1940. At the end of July 1940 he escaped from Belgium and fled to Clermont-Ferrand
, where the university of Strasbourg was re-organized.

At the end of December 1940, he met

Libération-Sud and Libération-Nord
. Cavaillès took an active part in editing the paper. The first edition appeared in July 1941.

In 1941, he was appointed professor at the Sorbonne and left Clermont-Ferrand for Paris, where he helped form the Libération-Nord resistance group, becoming part of its management committee.

In April 1942, at the instigation of Christian Pineau, the central Office of Information and Action (BCRA) of London charged him with the task of forming an intelligence network in the Northern Zone, known as "Cohors". He was ordered by Christian Pineau to pass into the Southern Zone, and Cavaillès headed the network and formed similar groups in Belgium and the north of France.

In September 1942 he was arrested with Pineau in

French police. After a failed escape attempt to London, he was interned in Montpellier at the Saint-Paul d' Eyjeaux prison camp from where he escaped at the end of December 1942. The book Cavaillès wrote in prison in Montpellier in 1942 was published posthumously in 1946, edited by the epistemologist Georges Canguilhem and the mathematician Charles Ehresmann
under the title Sur la logique et la theorie de la science.

Denounced as a public enemy by the

Vichy regime and sought by the police, he fled clandestinely to London in February 1943. There he met General Charles de Gaulle
on several occasions.

Back in France on 15 April he resigned from the management Committee of the Libération movement in order to dedicate himself entirely to direct action. He was in charge of the sabotage of the stores of the Kriegsmarine in Brittany and German radio installations on the coast.

Betrayed by one of his liaison officers[who?], he was arrested on 28 August 1943 in Paris with his sister[who?] and her brother-in-law[who?]. Tortured, imprisoned in Fresnes then in Compiègne, he was transferred to the Citadel from Arras and was reported as being executed there on 17 February 1944. New research in 2015 revealed this date was incorrect and he was sentenced and executed on 4 April 1944.[8] Buried at first in Arras under a wooden cross marked "unknown n°5", his body was exhumed in 1946 to be buried in the Crypt in the Sorbonne, in Paris.

Legacy

The Centre Cavaillès de l'

rue d'Ulm, as Centre for the Study of the History and Philosophy of Science. At the formal opening, philosopher Georges Canguilhem said, "A philosopher-mathematician loaded with explosives, lucid and reckless, resolute without optimism. If that's not a hero, what is a hero?" (Translated from the original French language: "Un philosophe mathématicien bourré d'explosifs, un lucide téméraire, un résolu sans optimisme. Si ce n'est pas un héros, qu'est-ce qu'un héros ?")[9]

Cavaillès is honored in the Heroes of the Resistance postage stamp set.

In

Luc Jardie
(the Chief) was in part inspired by Cavaillès. Jardie's chief operative, recuperating from injuries in a hideaway, has only five books; the title of each is a publication of Cavaillès, though the author is shown as "Luc Jardie."
