When cars got windshield wipers
Five years after Mary Anderson was issued her patent, car maker Henry Ford introduced his Ford Model T. Five years later, Ford introduced the moving assembly line, an innovation which drastically lessened the time it took to build the car and greatly reduced its cost to consumers.
As cars became ubiquitous across the U.S., manufacturers’ eyes were opened to the value of the windshield wiper. By the early 1920s, a version of Anderson’s invention became standard on most vehicles.
Anderson likely never earned any royalties or licensing fees since her U.S. Patent No. 743,801
expired in 1920. Indeed, car manufacturers didn’t use her exact design.
