During a trip to New York City, Alabama woman Mary Anderson noticed a trolley driver couldn’t see well when it was snowing.
At that point, drivers had to open the window to clear it, letting snow and rain into the vehicle.
As a solution, Anderson designed and patented wood and rubber arms that would push rain and snow off the window at the pull of a lever.
She was told her 1903 invention was distracting and impractical, and never profited off her design.
Planning a road trip? Now is probably a good time to check your own wipers – and the rest of these car parts.
