Eustache Juchereau de Saint-Denys

Eustache Jean Juchereau de Saint-Denys (March 28, 1809 – June 17, 1883), was a lawyer, diplomat, polyglot, correspondent and French legislator of French-Canadian origin, graduated from the Faculty of Law of the University of Paris. He was one of the leading French diplomats to the Dominican Republic during the Dominican War of Independence.

Coming from a family of noble lineage and legitimist orientation, he entered the French diplomatic service and developed his career in several European, Asian and American countries, including Greece, Turkey, Spain, Haiti and, especially, the newly born Dominican Republic. In December 1843, he participated, along with his colleagues Adolphe Barrot and André-Nicolas Levasseur, in the negotiations held in Port-au-Prince with several Dominican deputies present at the Haitian Constituent Assembly.

During the first months of the First Dominican Republic's existence, he maintained good relations with all of the rulers, without being influenced by personal sympathies. He forged bonds of respect and cooperation with members of the Central Government Board —among them Francisco del Rosario Sánchez, Tomás Bobadilla, and José María Caminero —although his most notable influence was exercised over Pedro Santana, a general who had come to power after the coup of July 1844 and who viewed the Duartistas with suspicion, a group rejected by the French consul. Saint-Denys established himself as one of the most influential figures in Santana's first government, alongside ministers and senior military commanders. After completing his mission in the Caribbean in 1847, he decided to retire from diplomatic life and returned to his hometown in Corsica, where he lived until his death on June 17, 1883.
