The warmth in your car on a cold day exists thanks to a woman's brilliant idea from over a century ago.
In 1893, a mechanical engineer named Margaret A. Wilcox patented the very first car heater.
At the time, driving was a brutally cold experience in the winter, especially in the open-air automobiles of the era.
Her design was simple yet revolutionary. It worked by channeling air over the hot engine and piping it into the front of the cabin to warm the driver and passengers.
This fundamental concept laid the groundwork for the modern car heating systems that we all rely on today.
But Margaret wasn't just focused on cars. She was a forward-thinking inventor with multiple patents to her name.
She also invented and patented a machine that could function as both a clothes washer and a dishwasher, showing her mind was always at work solving everyday problems.
While her name may not be as well-known as some of her male contemporaries, her practical inventions made a lasting impact on daily life. [Sources: U.S. Patent and Trademark Office, The Henry Ford Museum, National Women's History Museum]
