Lamarck, Jean Baptiste Pierre Antoine de Monet, chevalier de, 1744-1829, French naturalist. He is noted for his study and classification of invertebrates and for his introduction of evolutionary theories. After varied careers he turned his attention to botany, and recognition of his skill followed upon publication of Flore françoise (3 vol., 1778). He was elected to the Academy of Sciences, and, aided by Buffon, he traveled over Europe, under the title of royal botanist, visiting museums and collecting material for the museum of the academy. From 1793 he was professor of zoology at the Museum of Natural History. His ideas concerning the origin of species were first made public in his Système des animaux sans vertèbres (1801). He introduced the terms biology and Invertebrata and suggested the invertebrate classes Infusoria, Annelida, Crustacea, Arachnida, and Tunicata. He is also considered the founder of invertebrate paleontology. His later works were Philosophie zoologique (2 vol., 1809; tr. Zoological Philosophy, 1963) and Histoire naturelle des animaux sans vertèbres (7 vol. in 8, 1815-22). Blindness and poverty marred his later years. Lamarck's theory of evolution, or Lamarckism, asserts that all life forms have arisen by a continuous process of gradual modification throughout geologic history. To explain this process he cited the then generally accepted theory of acquired characteristics, which held that new traits in an organism develop because of a need created by the environment and that they are transmitted to its offspring. Although the latter hypothesis was disputed during Lamarck's lifetime by Cuvier and others and was rejected altogether as the principles of heredity were established, Lamarck's theory of evolution was an important forerunner of the work of Charles Darwin, who recognized a modified influence of environment in evolutionary processes.

Créquy or Créqui, François, chevalier de, c.1629-87, marshal of France. Having fought in the Thirty Years War and on the government side in the Fronde, he conducted brilliant campaigns in the War of Devolution (1667-68) and conquered Lorraine in 1670. He refused (1672) to serve under Marshal Turenne in the third Dutch War (1672-78) and was exiled but soon submitted. In 1675, he was captured after his defeat at Konzer Brücke near Trier. Released shortly after, he achieved military renown in Alsace. In 1684, Créquy occupied Luxembourg.
Chevalier, Michel, 1806-79, French economist. An ardent Saint-Simonian as a youth, he later favored a form of welfare capitalism. He advocated industrial development as the key to social progress. Also a proponent of free trade, he negotiated with Richard Cobden the Anglo-French trade treaty of 1860. His Lettres sur l'Amérique du Nord (1836) extols the United States.
Chevalier, Maurice, 1888-1972, French singer and film actor. He made his debut in 1900 singing and dancing at the Casino de Tourelles, Paris. As the dancing partner of Mistinguett and as the star of several Paris music halls, he won his public by his charm and inimitable smile; by 1928 his reputation was international. He became famous for his portrayal of the debonair man-about-town, typically sporting a straw hat and a cane. Among his later films are Love in the Afternoon (1956), Gigi (1958), Can-Can (1959), and Fanny (1961).

Chevalier, Guillaume Sulpice: see Gavarni.
French chevalier German Ritter

In the European Middle Ages, a formally professed cavalryman, generally a vassal holding land as a fief from the lord he served (see feudalism). At about 7 a boy bound for knighthood became a page, then at 12 a damoiseau (“lordling”), varlet, or valet, and subsequently a shieldbearer or esquire. When judged ready, he was dubbed knight by his lord in a solemn ceremony. The Christian ideal of knightly behavior (see chivalry) required devotion to the church, loyalty to military and feudal superiors, and preservation of personal honor. By the 16th century knighthood had become honorific rather than feudal or military.
