Josephine Garis Cochran
Born 1839 - Died August 3 1913
Patent No. 355, 139
Josephine Cochran invented the first practical dishwasher and formed the Garis-Cochran Dish-Washing Company to manufacture and market it.
Cochran was born in Ohio. After moving to Illinois, Cochran set out to design a washing device after commonly finding plateware chipped from hard washing. She designed a set of wire compartments, each created to fit plates, cups, or saucers. The compartments were placed inside a wheel that lay flat inside a copper boiler, while a motor turned the wheel, pumping hot soapy water from the bottom of the boiler. The machine was showcased in the World Columbian Exposition of 1893, helping to establish a market for the dishwasher in hotels and large restaurants.
