I don't usually post these, but I thought this was interesting. From the "Uncle John's Bathroom Reader Calendar:"
"In 1903 Mary Anderson took a trip to New York City from her home in Alabama. One snowy afternoon she decided to tour the city by streetcar, but instead of sightseeing found herself staring at the streetcar conductor, who had to keep stopping to wipe the snow off his windshield. On the spot, Anderson made a drawing in her sketchbook of a device consisting of a lever that 'activated a swinging arm that mechanically swept off the ice and snow' from the windshield. She got her patent the following year; ten years later windshield wipers were standard equipment on automobiles." www.pageaday.com Duane 72 Cutlass Convertible
