Disposable Diapers
The diapers we all know and love today were actually invented by a woman named Marion Donovan. Her initial design was mostly a waterproof diaper cover, but after selling her patent for $1 million, it was upgraded to a disposable model.
Computers
The computer was invented by Howard Aiken and Grace Hopper, back in 1944. Hopper was actually the one responsible for the word “bug”, as it at the time quite literally meant that there were moths in the computer that needed debugging.
