Clara McAdow (1838–1896) was an American women's suffragist and mine owner. Born in Ohio, she grew up in Jackson, Michigan, relocating to Montana with her first husband, C. E. Tomlinson. When Tomlinson died, she took their savings and invested in real estate in Billings. Through her real-estate ventures, she met her second husband, Perry McAdow. She purchased from him the Spotted Horse mine, which he had received as payment for a debt. Clara took charge of all aspects of the mine, directing all of its operations and often living on site. McAdow was intensely interested in the women's suffrage movement, hosting Carrie Chapman Catt and Susan B. Anthony in her home to promote giving women the vote.Photograph credit: unknown; restored by Adam Cuerden
