This stereograph (stereoview) was made from real photographs in 1898 by commercial photographer Truman Ward Ingersoll (1862-1922) of St. Paul, Minnesota. Ingersoll produced many images of Ojibwe (Chippewa) people and their ways of life in northern Minnesota. I was unable to find additional information about the couple in this portrait. In the Library of Congress’s online catalog of prints and photographs, the man’s name is hyphenated Maza-i-casuawin. The Ingersoll stereographs in the Library’s holdings have not been digitized.
Around 1898 Ingersoll began to reproduce some of his stereographs using a cheaper photolithographic process, sometimes adding colors to the prints afterward. He reissued this image using that process under the same title but with the man’s name spelled Mazaicasuanin, replacing the letter w with n. An illustrated article about Truman Ingersoll and the history of stereography, written in 1980 by Patricia Condon Johnston for the Minnesota Historical Society, can be read or downloaded as a pdf here.
