Laura Cornelius Kellogg was an Oneida activist, author, orator and policy reformer, and she was one of the founding members of the Society of American Indians (SAI) in 1911. SAI was the first national American Indian rights organization run by and for American Indians. Other organizations believed that total assimilation into American society was the only way to “save” the Indians, but many Progressive Era Indians and members of SAI fought to preserve Native rights and sovereignty. Kellogg was an advocate against increasingly stringent federal Indian policies that, among other things, sent Native children to boarding schools and sought to eradicate Native languages, cultures, and political, economic and social systems. Kellogg left a controversial legacy — one contemporary called her a “cyclone,” while another called her “a woman of brilliance” — but hers is a fascinating story of a Native woman in the late 19th and early 20th centuries.
