Josephine Cochrane (1839 – 1913)
The first reliable (handpowered) dishwasher was invented in 1887 by Josephine Cochrane with the help of George Butters and was unveiled at the 1893 Chicago World’s Fair. Cochrane was quite wealthy and never washed dishes herself; she reportedly invented the dishwasher because her servants were chipping her fine china.
When she couldn’t find one, she built it herself. She said : “if you want something done right you better do it yourself“.
