Ludovic Zoretti

Ludovic Zoretti (born June 29, 1880 in Marseille , † January 22, 1948 in Carrère, Lot-et-Garonne ) was a French mathematician, trade unionist and politician.

Zoretti attended the Lyceum in Marseille and in 1899 was second in the national exams for the École polytechique and first for the École normal supérieure . In 1902 he graduated from the École normal supérieure ( Agrégation ) and was then a librarian there. From 1904 to 1908 he was a high school teacher in Rochefort, where he also received his doctorate in 1905 ( Sur les fonctions analytiques uniformes qui possèdent un ensemble parfait discontinu de points singuliers , Gauthiers-Villars 1905). From 1908 to 1911 he was Maître de conférences at the University of Grenoble and from 1911 to 1939 Professor of Mechanics at the Faculté des Sciences at the University of Caen .

He wrote early papers on set topology and the article point sets in the Encyclopedia of Mathematical Sciences .

He was also an active trade unionist (from 1917 to 1940 belonging to the CGT ), especially for teachers and at universities, and in the Socialist Party. From 1928 to 1939 he was secretary of the Fédération Générale de l'Enseignement , where he advocated a single school.

From 1914 to 1939 he was a member of the Section française de l'Internationale ouvrière (SFIO). As a staunch pacifist (who also vehemently defended his views at the SFIO congress in Nantes in 1939), he lost his offices in 1939 (at the university and with the SFIO) and was even tried in a military tribunal in 1940. During the time of the occupation, he joined the Rassemblement national populaire (RNP) of Marcel Déat, which collaborated with the Germans and the Vichy regime, in a leading position (member of the fifteen-member board of directors and delegate for the southern zone). He was not reintegrated into teaching until 1944. After the war he was sentenced to death first, which was then changed to 8 years imprisonment. He died in an internment camp.
