Julien Dubuque (January 1762 – 24 March 1810) was a French Canadian of Normandy origin from the area of Champlain, Quebec who arrived near what now is known as Dubuque, Iowa, which was named after him. He was one of the first European men to settle in the area. He initially received permission from the Mesquakie Indian tribe to mine the lead in 1788, which was confirmed by the Spanish, who gave him a land grant in 1796. After his death, the Mesquakie built a log crypt for Dubuque, which was replaced in the late 19th century by an imposing stone monument.
