François Sébastien Letourneux (1752–1814) was a French lawyer and politician who was Minister of the Interior under the Directory.
He replaced François de Neufchâteau, who had been appointed a member of the Directory.
[2][1] Letourneux, who was inexperienced in national politics, was responsible for enforcing the new republican calendar, with its ten-day weeks.
This included finding ways to ensure the calendar was adopted, while holding back over-zealous local officials who wanted, for example, to close churches on the old Sundays and religious holidays.
[3] Under Letourneux's administration the Directory issued the decree of 27 Brumaire Year VI in support of public education, and the decree of 17 Pluviôse year VI requiring special supervision of private educational establishments.
