In this succinct dual biography, Laura Chmielewski demonstrates how the lives of two French explorers – Jacques Marquette, a Jesuit missionary, and Louis Jolliet, a fur trapper – reveal the diverse world of early America. Following the explorers' epic journey through the center of the American continent, Marquette and Jolliet combines a story of discovery and encounter with the insights derived from recent historical scholarship. The story provides perspective on the different methods and goals of colonization and the role of Native Americans as active participants in this complex and uneven process.
