On December 28, 1886 a patent was issued to Josephine Garis Chochrane from Shelbyville, Illinois for what is considered the first practical mechanical dish washing machine. It was displayed at the 1893 Chicago World’s Fair but saw use mostly in commercial settings. It was not until the late 1940’s that a home model came on the scene. Cochrane’s original company is now a part of Whirlpool Corporation.
