Hart Merriam Schultz, also known by his Blackfoot name, Lone Wolf (Nitoh Mahkwii or Ni-tah-mah-kwi-i), was an Indian artist of the twentieth century.
Most of his work was done in either Arizona or Montana, after he completed his artistic studies in Los Angeles and Chicago.
He would spend his summers in a tipi studio in Montana, and his winters in Arizona, either in Tucson, or at the studio his father created for him at Butterfly Lodge, near Eagar.
