Born in 1815, Ada Lovelace was the daughter of poet Lord Byron, but it was her mother who encouraged her to pursue mathematics. When she was about 17, Lovelace befriended inventor Charles Babbage, who’s famous for being the “father of the computer.” Translating a French article for her mentor, Lovelace added her own notes, which were three times longer than the original article. Her work on how to code a computer (which hadn’t been built yet) to use letters and numbers was published in 1843 under “A.A.L.,” locking her place in history as the first computer programmer.

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.
