I expected the dishwasher to be invented by a woman but this story has a twist.
Josephine Cochrane was a socialite that didn`t invent the dishwasher because she was tired of doing the dishes. She didn`t do dishes! She invented it because she was tired of staff that broke her fine china.
How about that?
