Saturday in Duluth will be Ethel Ray Nance Day, the birthday of a Duluth-born civil rights activist who would have been 125 years old. Her father established the Duluth branch of the NAACP in 1920 after three Black men were lynched in the city. Ethel carved her own path, becoming the first Black woman to work as a stenographer at the state legislature, an executive secretary for W.E.B DuBois and one of the first black policewomen in Minnesota. She has been an unsung hero until now. Her story is now being published by her granddaughter, Karen Nance, the author of “Ethel Ray: Living in the White, Gray and Black”. MPR News host Cathy Wurzer talked with Karen Nance about her grandmother and the book, out Saturday.
