Jean-Baptiste Le Moyne de Bienville (; ; February 23, 1680 – March 7, 1767), also known as Sieur de Bienville, was a French colonial administrator in New France. Born in Montreal, he was an early governor of French Louisiana, appointed four separate times during 1701–1743. He was the younger brother of explorer Pierre Le Moyne d'Iberville. Early life Jean-Baptiste Le Moyne was the son of Charles le Moyne, born in Longueil, near Dieppe, and Catherine Primot (also known as Catherine Thierry), born in Rouen, both cities in the Province of Normandy. Charles le Moyne established his family in the settlement of Ville-Marie (present day Montreal) at an early age and had fourteen children total. Exploration in the New World At the age of seventeen, Bienville joined his brother Iberville on an expedition to establish the colony of Louisiana. Bienville explored the Gulf of Mexico coastline, he discovered around approximately 1699 as far up as into Mobile Bay which was not deep enough to go any further, founded Belle Fontaine they had discovered an artesian spring bubbling and leaping from the beach. This spring is now 300–400 feet out into Mobile Bay. Bienville played a huge role in founding part of the coast line in Mobile, Alabama. He then went on to discovering the Chandeleur Islands off the coast of Louisiana as well as Cat Island and Ship Island off the coast of what is now the state of Mississippi before moving westward to sail up the mouth of the Mississippi River. Eventually, the expedition ventured all the way to what is now Baton Rouge and False River. Before heading back to France, Iberville established the first settlement of the Louisiana colony, in April 1699 as Fort Maurepas or Old Biloxi (at present-day Ocean Springs, Mississippi), and appointed Sauvolle de la Villantry as the governor with Bienville as Lieutenant. Following Iberville's departure, Bienville took another expedition up the Mississippi River and encountered English ships at what is now known as English Turn. Upon hearing of this encounter on his return, Iberville ordered Bienville to establish a settlement along the Mississippi River at the first solid ground he could find. Fifty miles upriver, Bienville established Fort de la Boulaye. Co-founder of Mobile On the recommendations of his brother, Bienville moved the majority of the settlers to a new settlement in what is now Alabama on the west side of the Mobile River,
