Born in Detroit, Coquillard was an explorer and fur trader. He was a veteran of the War of 1812, serving under Major General William Henry Harrison. In 1823, he moved to Indiana’s St. Joseph River Valley and established a trading post near fellow American Fur Company agent Pierre Frieschutz Navarre. Trading with local Potawatomi and Miami communities, Coquillard became one of the most successful businessmen in Indiana and later founder of South Bend, Indiana.
