Honoring women’s history month. Josephine Cochrane invented first automated dishwasher.

This dishwasher model was presented at the Chicago World’s Fair in 1893. Josephine Cochrane used the original design, but advanced the invention to create the first automated dishwasher.

The Cochrane dishwasher featured a copper boiler that contained a wooden wheel. The dishwasher motor could be driven by hand using a pulley or powered.

This allowed the dishes that were fitted into wired compartments to be spun and sprayed with soapy water. Although Cochrane didn’t wash any dishes herself, she claimed her dishes were often chipped by servants, and her dishwasher simplified the process, reducing the potential for damage.
