Dishwasher

Yes, you read that title correctly. The Dishwasher was invented in 1850 by Joel Houghton but it didn't work very well. In 1886 Mrs. Josephine Cochran made the first practical dishwasher. In the 1893 World's Fair Mrs. Josephine Cochran won the highest prize for "best Mechanical construction." Restaurants and hotels were the first purchasers. Her company eventually became a part of KitchenAid.
