Henry Rowe Schoolcraft (March 28, 1793 – December 10, 1864) was an American geographer, geologist, and ethnologist, noted for his early studies of Native American cultures, as well as for his 1832 expedition to the source of the Mississippi River. He is also noted for his major six-volume study of Native Americans commissioned by Congress and published in the 1850s.
He served as United States Indian agent in Michigan for a period beginning in 1822. During this period, he named several newly organized counties, often creating neologisms that he claimed were derived from indigenous languages.
There he married Jane Johnston, daughter of a prominent Scotch-Irish fur trader and an Ojibwe mother, who was the high-ranking daughter of Waubojeeg, a war chief. Jane lived with her family in Sault Ste. Marie, Michigan. She was bilingual and educated, having grown up in a literate household. Jane taught Schoolcraft the Ojibwe language and much about her maternal culture. They had several children together, only two of whom survived past childhood.
