In 1886 Josephine Cochrane (1839-1913), a woman from Shelbyville, Illinois made the first practical mechanical dishwasher.
Though Cochrane was rich, had never washed dishes herself and had servants, she wanted a machine that could get the job done quickly and without damaging the crockery.
As nothing of the sort existed, she made one herself!
She was successful, and others started requesting dishwashing machines. Her machines started being used in restaurants in Illinios. After patenting her design, she went into business. Today her company has become part of the Whirlpool brand.
