Fausto de Elhuyar (11 October 1755 – 6 February 1833) was a Spanish chemist, and the first to isolate tungsten with his brother Juan José Elhuyar in 1783. He was in charge, under a King of Spain commission, of organizing the School of Mines in México City and so was responsible for building an architectural jewel known as the "Palacio de Minería". Elhuyar left Mexico after the Mexican War of Independence, when most of the Spanish residents in Mexico were expelled.
Michel Ordener (French pronunciation: [miʃɛl ɔʁdənɛːʁ]; 2 September 1755 – 30 August 1811) was a French general of division and a commander in Napoleon's elite Imperial Guard. Of plebeian origins, he was born in L'Hôpital and enlisted as private at the age of 18 years in the Prince Condé's Legion. He was promoted through the ranks; as warrant officer of a regiment of Chasseurs à Cheval, he embraced the French Revolution in 1789. He advanced quickly through the officer ranks during the French Revolutionary Wars.
In 1804, Ordener organized and led the controversial kidnapping of the Duke d'Enghien. In 1805, he commanded a regiment of the Imperial Guard cavalry at several important battles, including the Battle of Austerlitz; although he led an energetic and opportune charge, Napoleon noted that Ordener seemed tired and predicted that the general would last only five or six years more. Ordener participated in one more campaign and then accepted a post in the Senate. Napoleon appointed him as Josephine Bonaparte's equerry, supervising the care and maintenance of her horses. He followed this with the post as governor of the Emperor's household in Compiegne, where Ordener died on 30 August 1811.
