In March 1839 after the dissolution of the chamber by
Louis Philippe, he was elected deputy for Paris (re-elected in 1842 and in 1846), and sat in the group of the Radical
Left, being one of the leaders of the party hostile to Louis Philippe. On 24 February 1848 he pronounced in favour of the republic.
Alphonse de Lamartine chose him as minister of education in the provisional government, and Carnot set to work to organize the primary school systems, proposing a law for obligatory and free primary instruction, and another for the
secondary education of girls. He opposed purely secular schools, holding that "the minister and the schoolmaster are the two columns on which rests the edifice of the republic." By this attitude he alienated both the Right and the Republicans of the Extreme Left, and was forced to resign on 5 July 1848. He was one of those who protested against the ''coup d'état'' of 2 December 1851 but was not proscribed by
Louis Napoleon. He refused to sit in the Corps Législatif until 1864, in order not to have to take the oath to the emperor. From 1864 to 1869 he was in the republican opposition, taking a very active part. He was defeated at the election of 1869. On 8 February 1871 he was elected deputy for the
Seine-et-Oise département. He joined the
Gauche républicaine parliamentary group and participated in the drawing up of the Constitutional Laws of 1875. On 16 December 1875 he was named by the National Assembly
senator for life. He died three months after the election of his elder son,
Marie François Sadi Carnot, to the presidency of the republic. He had published ''Le Ministère de l'Instruction Publique et des Cultes, depuis le 24 février jusqu'au 5 juillet 1848
, Mémoires sur Carnot par son fils
(2 vols., 1861–1864), Mémoires de Barère de Vieuzac'' (with
David d'Angers, 4 vols 1842–1843). His second son,
Marie Adolphe Carnot (b. 1830), became a distinguished mining engineer and director of the
École des Mines (1899), his studies in analytical chemistry placing him in the front rank of French scientists. He was made a member of the Academy of Sciences in 1895. == References ==
