Henri Bergson was born on 18 October 1859 in Paris. One of the most influential French philosophers of the late nineteenth and early twentieth centuries, his most enduring contribution is his concept of multiplicity. He began teaching in Angers at the lycée in 1881, and then moved to the University Clermont-Ferrand. In 1881, he accepted a teaching post at the Lycée Henri-Quatre, followed by École Normale, becoming Professor in 1898. He was appointed Chair of Ancient Philosophy at Collège de France in 1900, where he remained until his retirement.
Elected a member of the French Academy in 1914, he was awarded the Nobel Prize in Literature in 1927. In defiance of the Nazis and their conquest of France, Bergson gave up all positions and renounced his many honours shortly before his death. Notable works include La Philosophie de la Poesie: le Génie de Lucrèce (1884), Essai sur les données immédiates de la conscience (1889), Matière et mémoire (1896), Le rire (1900), L’Évolution créatrice (1907), L’Énergie spirituelle (1919), Durée et simultanéité (1922), and Les Deux Sources de la Morale et de la Religion (1932).
