First Automatic Dishwasher

In 1850, Joel Houghton patented the first automatic dishwasher a wooden machine with a hand-turned wheel that splashed water on dishes. It wasn't much, but it was the first patent. In 1886, Josephine Cochran invented the first practical dishwasher. It was also hand operated. Dishwashers did not become household items until the 1950s.
