The wealthy socialite Josephine Cochrane wanted to protect her china while it was being washed, because when her servants were washing it by hand, sometimes it would get damaged. And her view was that if you want a job done well, you have to do it yourself. So she did. She invented the first practical and commercially successful dishwasher. The patent was issued in 1886. Cochrane designed it in the shed behind her house and built it with the assistance of mechanic George Butters. Her dishwasher was the first to use water pressure instead of scrubbers. It also had compartments, each specially designed to fit either plates, cups, or saucers.
