Women’s History Month: 3 Things You Didn’t Know Women Invented

March is Women’s History Month and we wanted to pay homage to some pretty creative women inventors. Some of these women created inventions may surprise you! This is a sample from a list created by How Stuff Works, click here to read their entire article.

1. Circular Saw

Tabitha Babbitt lived in a Shaker community in Massachusetts and worked as a weaver, but in 1810, she came up with a way to lighten the load of her brethren. She observed men cutting wood with a pit saw, which is a two-handled saw that requires two men to pull it back and forth. Though the saw is pulled both ways, it only cuts wood when it’s pulled forward; the return stroke is useless. To Babbitt, that was wasted energy, so she created a prototype of the circular saw that would go on to be used in saw mills. She attached a circular blade to her spinning wheel so that every movement of the saw produced results. Because of Shaker precepts, Babbitt didn’t apply for a patent for the circular saw she created.

2. The Compiler and COBOL Computer Language
Admiral Grace Murray Hopper (pictured above) joined the military in 1943 and was stationed at Harvard University, where she worked on IBM’s Harvard Mark I computer, the first large-scale computer in the United States. She was the third person to program this computer, and she wrote a manual of operations that lit the path for those that followed her. In the 1950s, Admiral Hopper invented the compiler, which translates English commands into computer code. This device meant that programmers could create code more easily and with fewer errors. Hopper’s second compiler, the Flow-Matic, was used to program UNIVAC I and II, which were the first computers available commercially. Admiral Hopper also oversaw the development of the Common Business-Oriented Language (COBOL), one of the first computer programming languages. Admiral Hopper received numerous awards for her work, including the honor of having a U.S. warship named after her.

3. Windshield Wiper

At the dawn of the 20th century, Mary Anderson went to New York City for the first time. She saw a much different New York City than the one tourists see today. There were no cabs honking, nor were there thousands of cars vying for position in afternoon traffic. Cars had not yet captured the American imagination and were quite rare when Anderson took that trip, but the woman from Alabama would end up inventing something that has become standard on every automobile. During her trip, Anderson took a tram through the snow-covered city.She noticed that the driver had to stop the tram every few minutes to wipe the snow off his front window. At the time, all drivers had to do so; rain and snow were thought to be things drivers had to deal with, even though they resulted in poor visibility. When she returned home, Anderson developed a squeegee on a spindle that was attached to a handle on the inside of the vehicle. When the driver needed to clear the glass, he simply pulled on the handle and the squeegee wiped the precipitation from the windshield. Anderson received the patent for her device in 1903; just 10 years later, thousands of Americans owned a car with her invention.
