Antoine Laumet was born in this house on March 5, 1658. Laumet became le Sieur de la Mothe Cadillac. On July 24, 1701, he founded the settlement that became Detroit, Michigan, United States of America. Accompanied by one hundred troops of the Compagnie Franche de la Marine and nearly as many Indians, Cadillac claimed Detroit in the name of King Louis XIV, who had directed him to establish forts connecting Quebec and New Orleans. Cadillac brought his family to Detroit and remained there until 1710. In 1717, after serving as Governor of Louisiana, he returned to France. He died in Castelsarrasin in 1730. In 1972 the Detroit Historical Commission and Society gave the village of St. Nicholas-de-la-Grave twenty thousand dollars to purchase and help restore this house as a museum.
