1 mar 1850 ano - Joel Houghton was granted the first dishwasher patent in 1850. The machine was made of wood and required you to hand-turn a wheel that caused water to splash on the dishes.
Houghton's machine barely worked. The first practical dishwasher was invented by a woman named Josephine Cochran in 1886.
Dishwashers, however, did not begin appearing in homes until the 1950s.
