While the windshield wiper became increasingly common, there is limited information available regarding Mary Anderson's activities and financial situation in her later years. She seemingly did not achieve significant financial success from her invention, unlike many later inventors of automotive technologies.

Mary Elizabeth Anderson passed away at her summer home in Monteagle, Tennessee, at the age of 87. Her contributions to automotive safety were largely unrecognized during her lifetime.

In recent decades, Mary Anderson's invention has gained greater recognition. She is now widely acknowledged as the inventor of the windshield wiper, and her story serves as an inspiration for female inventors and entrepreneurs. Her contribution is now noted in numerous biographies, articles, and educational materials highlighting her innovation.
