Nancy Green (March 4, 1834 – August 30, 1923) was an American former slave, who, as "Aunt Jemima", was one of the first African-American models hired to promote a corporate trademark.

[3][4][5] Nancy Green has been variously described as a servant, nurse, nanny, housekeeper, and cook for Samuel Johnson Walker and his wife Amanda.

[7] The Walker family initially settled in a swank residential district near Ashland Avenue and Washington Boulevard called the "Kentucky Colony", then home to many transplanted Kentuckians.

[7] On the recommendation of Judge Walker,[8] she was hired by the R.T. Davis Milling Company in St. Joseph, Missouri, to represent "Aunt Jemima", an advertising character named after a song from a minstrel show.

[8][10][11][12] After the Expo, Green was reportedly offered a lifetime contract to adopt the Aunt Jemima moniker and promote the pancake mix; however, she would only choose to serve in the position for twenty years.

[1][13] This marked the beginning of a major promotional push by the company that included thousands of personal appearances and Aunt Jemima merchandising.

[15] After Green's death other women were hired by Quaker Oats to portray the role of Aunt Jemima, including Lillian Richard.

[1][18] Green died on August 30, 1923, at the age of 89 in Chicago, when a car driven by pharmacist Dr. H. S. Seymour collided with a laundry truck and "hurtled" onto the sidewalk where she was standing.

[23][24] In 2014, a lawsuit was filed against Quaker Oats, PepsiCo, and others, claiming that Green and Anna Short Harrington (who portrayed Aunt Jemima starting in 1935) were exploited by the company and cheated out of the monetary compensation they were promised.
