Biography

De Lanessan was born in Saint-André-de-Cubzac in the Gironde departments of France, department of France and entered the French Navy in 1880, serving on the East African and Cochin-China stations in the medical department until the Franco-Prussian War, when he resigned and volunteered for the army medical service. He then completed his studies, taking his doctorate in 1882. Elected to the Municipal Council of Paris in 1879, de Lanessan declared in favor of communal autonomy and joined with Henri Rochefort in demanding the erection of a monument to the Communards; but after his election to the Chamber of Deputies of France, Chamber of Deputies for the 5th arrondissement of Paris in 1881 he gradually veered from the extreme Radical party to the Republican Union (France), Republican Union, and identified himself with the cause of colonial expansion. A government mission to the French colonies in 1886-1887, in connection with the approaching Exposition Universelle (1889), Paris exhibition, gave him the opportunity of studying colonial questions, on which, after his return, he published three works: ''La Tunisie'' (Paris, 1887); ''L'Expansion coloniale de la France'' (ib., 1888), ''L'Indo-Chine francaise'' (ib., 1889). In 1891 he was made civil and Governor-General of French Indochina, military governor of French Indochina, where his administration, which led to open rupture with Admiral Fournier, was severely criticized. Nevertheless, he consolidated French influence in Annam (French protectorate), Annam and Cambodia, and secured a large accession of territory on the Mekong River from the kingdom of Siam. He was recalled in 1894, and published an apology for his administration (''La Colonisation francaise en Indo-Chine'') in the following year. In the Waldeck-Rousseau cabinet of 1899 to 1902 he was Minister of Marine, and in 1901 he secured the passage of a naval programme intended to raise the French navy during the next six years to a level befitting the place of France among the great powers. At the general election of 1906 he was not re-elected. He was political director of the Siècle, and president of the French Colonization Society, and wrote, besides the books already mentioned, various works on political and biological questions. He retired in French Indochina, where it was rumored that he had an illegitimate child with a Vietnamese people, Vietnamese woman. De Lanessan was an advocate of Lamarckism, neo-Lamarckian evolution.Maienschein, Jane; Ruse, Michael. (1999). ''Biology and the Foundations of Ethics''. Cambridge University Press. p. 86. "Edmond Perrier, Jean de Lanessan, Alfred Giard, and Felix Le Dantec popularized a neo-Lamarckian biology that stressed the inheritance of acquired characteristics and the influence of the environment on living organisms."
