Don Alejandro María Aguado y Ramírez de Estenoz, 1st Marquis de Las Marismas del Guadalquivir was a Spanish banker and born of Old Christian parentage. Originally from La Rioja, at Seville. He began life as a soldier, fighting with distinction in the Spanish War of Independence first against French, then on on the side of Joseph Bonaparte. After the Battle of Baylen (1808) he entered the French army, in which he rose to be colonel and aide-de-camp to Marshal Soult. He was exiled in 1815, and immediately started business as a commission-agent in Paris, where, chiefly through his family connexions in Havana and Mexico, he acquired in a few years enough wealth to enable him to undertake banking. The Spanish government gave him full powers to negotiate the loans of 1823, 1828, 1830 and 1831; and Ferdinand VII. rewarded him with the title of marquis, the decorations of several orders and valuable mining concessions in Spain. Aguado also negotiated the Greek loan of 1834. In 1828, having become possessed of large estates in France, including the Château Margaux, famous for its wine, he was naturalized as a French citizen. He died at in Spain on April 14, 1842, leaving a fortune 'computed at 60,000,000 francs, and a splendid collection of pictures which at his death was sold by auction.∼Banquero español, nacido Alejandro María de Aguado y Ramírez de Estenoz.
