Jackson Kemper (December 24, 1789 – May 24, 1870) in 1835 became the first missionary bishop of the Episcopal Church in the United States of America.
Especially known for his work with Native American peoples, he also founded parishes in what in his youth was considered the Northwest Territory and later became known as the "Old Northwest" (Indiana, Missouri, Wisconsin, Minnesota and Nebraska), hence one appellation as bishop of the "Whole Northwest".
Bishop Kemper founded Nashotah House and Racine College in Wisconsin, and from 1859 until his death served as the first bishop of the Diocese of Wisconsin.
