I just found this on msn.com
"When Josephine Cochran ordered her servants aside and began washing her own dishes, she had a revelation: washing dishes was true drudgery. This realization is what led Cochran to invent the first hand-turned dishwasher that used water pressure for cleaning. She succeeded in creating a working model, and patented it in 1886. The dishwasher eventually included a motor, and the larger model could clean 240 dishes in two minutes; as a result, it became popular with hotels and restaurants.
After Cochran's death in 1913, the company continued to manufacture dishwashers and, through several acquisitions, eventually came to be known under the KitchenAid brand. "
