Biography

Son of King Louis-Philippe of France (1773-1850)
Father of Pierre Philippe Jean Marie d'Orléans (November 4, 1845 — July 17, 1919), Duke of Penthièvre
He was a naval officer and a military writer prominent in modernizing the French Navy.
He joined the navy in 1831, became a lieutenant in 1836, and was named vice admiral in 1844. He wrote an article in the Revue des Deux Mondes which negatively compared the French naval forces to the English navy. His solution to this problem was the use of steamships, which he urged France to buy. 

In 1861 he traveled to the "United States to offer his services to President Lincoln. Returning to France in 1870, he was expelled, returned under the name of Colonel Lutherod, and was exiled again, but the law that exiled the Orléans family was repealed in 1871. Elected deputy of Haute-Marne in 1871, he retired from public life in 1875. His works include Essais sur la marine française (1852; “Essays on the French Navy”) and Études sur la marine, 2 vol. (1859; “Naval Studies”)."
