Jean Mistler (1 September 1897 – 11 November 1988) was a French writer born in Sorèze, Tarn. In 1966 he was elected to the Académie française.
Mistler, whose father's family had left Alsace in 1871, did his schooling in Sorèze, before preparing for the entrance examination of the Ecole Nationale Supérieure at the Lycée Henri IV, where he read philosophy under Alain. Mistler was drafted into the artillery in 1915 and emerged from World War I a staunch pacifist. He was accepted at the École normale in 1919 and came in first in the national Aggrégation exam in German the following year.
Instead of becoming a teacher in France, Mistler applied for a position abroad through the Ministry for Foreign Affairs. He was sent to the French legation in Hungary, becoming a cultural attaché, and teaching at the university of Budapest. In 1925 he was accepted into the Quai d'Orsay (Service des Oeuvres), where he succeeded Paul Morand.
He started a political career in 1928 when he was elected deputé of Aude under the radical socialist label. He received the appointment of under-secretary in charge of the Arts and served as a minister several times, starting in 1932. In 1934, he joined the government of Albert Sarraut, as Minister overseeing the postal service and telecommunications. A music lover, he founded the Orchestre national de la Radiodiffusion française (the ancestor of today's Orchestre National de France). From 1936, he chaired the Foreign Affairs Commission.
In parallel with his political activities, Mistler had begun a career as a writer, with the publication of Châteaux en Bavière (1925) and Ethelka (1929).
On 10 July 1940, in his role as the chair of the voting commission, Mistler introduced before the Parliament the bill that conferred the full powers to Marshal Philippe Pétain (with the ultimate objective of preparing a new constitution). This led critics to accuse him, after the war, of having been the "sinker of the Republic."
