Description: |
| This is the original patent for the windshield wiper. It was intended for use on trolleys and was hand-operated rather than motorized. By the time that Cadillac began offering them as standard equipment on their cars, in 1922, this patent had already expired. Despite efforts to license her invention, Mary Anderson never made any money from it. |
