Mary Anderson and her patented design
An Alabaman woman by the name of Mary Anderson happened to be visiting New York City in early 1902. NYC is particularly beautiful in the winter, but the views were obscured because snow was covering the trolley windows. Disturbingly, she noticed that the drivers had to periodically get out to clear off the fluffy white stuff by hand, or (yikes!) stick their heads out the side to see.
That's when Anderson brainstormed a squeegee-inspired device that would feature a spring-loaded arm and a rubber blade
attached to the outside of a vehicle, operable via a handle from the interior to move the arm and clear the glass. In other words, it was the world's first windshield wiper. She filed a patent in 1903, although her invention was too far ahead of its time and wouldn't see widespread adoption until more than a decade later, when automobile usage began to become widespread and companies began marketing wipers.
Fast-forward to 1917, when another woman, Charlotte Bridgwood, an engineer and president of a small manufacturing company in New York, took Anderson's idea one step further. Rather than relying on a manual hand crank to use the wiper, Bridgwood came up with an automated design that drew power directly from the vehicle engine.
Called the Electric Storm Windshield Cleaner (what a name!), it utilized a series of rollers instead of blades to perform a similar task. Like Anderson, Bridgwood did not see commercial success with her creation.

In 1953, a grisly Champagne cork accident left Robert Kearns with sight in only one eye. Afterwards, the Wayne State University engineering instructor started thinking more critically of how an eyelid works. “God doesn't have eyelids move continuously. They blink," he said in a newspaper interview. Kearns then set out to marry that insight with the workings of the windshield wiper.
After years of tinkering in a home laboratory, he secured several patents and then approached the neighboring Ford Motor Company with his masterpiece: an intermittent wiper that would activate at pre-set intervals. Following several meetings, Ford was eventually the initial automaker to roll out a model boasting the technology, and later many would follow. Kearns never received credit or compensation, until the 1990, after a winning a years-long lawsuit against Ford for patent infringement. Kearns had a fascinating life, and his story was turned into a movie, "Flash of Genius
," starring Greg Kinnear.
