Who invented our window's waving wipers?
Mary Anderson's windshield wiper. A true how-it-works story for kids 4–8.
The Mary Anderson story, read aloud
Here in our car, look at the bottom of the big front window. See those long skinny arms? Those are windshield wipers, and they push rain off the glass. Who thought of them? A lady named Mary Anderson! Long ago, when your great-great-grandparents were little, Mary rode a streetcar in New York City.
That's like a bus on train tracks. It was snowing, and snow covered the front window. The driver couldn't see! He kept stopping to open his window and wipe with his hand. Brr, icy fingers! So Mary had an idea.
She made an arm with a rubber edge that sat outside the window. The driver pulled a handle inside, and the arm swept the snow away, whoosh. He stayed warm and dry. At first, nobody wanted to buy it. But today, almost every car has wipers, just like ours.
