D.W. Hunter, the great grandson of Anna Short Harrington, the woman known as Aunt Jemima, has filed a class action lawsuit against PepsiCo, The Quaker Oats Company, Pinnacle Foods Group and The Hillshire Brands Company on behalf of all of her great grandchildren. He is seeking $2 billion, plus punitive damages to be determined at trial.

Hunter alleges that the companies conspired to deny that Harrington had been an employee of Quaker Oats, all the while exploiting her image and recipes for profit, but refusing to pay an “equitable fair share of royalties” to her heirs for more than 60 years.

The claims come on the heels of the defendants allegedly receiving a certified death certificate for Harrington that listed Quaker Oats as her employer. Hunter further alleges that the companies have lied by claiming they could not find any employment records for Harrington, or images of her, yet they had her image deposited inside the U.S. Patent and Trademark Office, according to the document.

Harrington took on the role of the pre-existing character of Aunt Jemima in 1935. In 1937, the company first registered the trademark for the brand. She was allegedly selected because of her own pancake recipe, which the company recreated for the mass market.

According to the suit, Quaker Oats sought out Harrington’s youngest daughter Olivia Hunter in 1989, ultimately using her likeness to update the look of Aunt Jemima. It is this image that is used today on Aunt Jemima-branded products.

The suit further alleges a racial element to the exploitation of Harrington and the other women who portrayed Aunt Jemima, going so far as to accuse the company of theft in procuring 64 original formulas and 22 menus from Harrington. It further alleges that Harrington was dissuaded from using a lawyer, exploiting her lack of education and age, so that the company could not pay her a percentage of sales from her recipes.

The company continued to use Harrington’s image for years, as well as licensing it out to other companies for ancillary merchandise like mugs and clothing.

The lawsuit cites Screen Actors Guild residuals and standard policies in the entertainment industry regarding revenue statements, which neither Harrington nor her heirs ever received. It wasn’t until they uncovered in 2013 that Quaker Oats had trademarked Harrington’s likeness and picture in 1937 that the family determined that they were owed royalties.
