“If nobody else is going to invent a dishwashing machine, I’ll do it myself,” were the renowned words of an Illinois woman whose invention impacted domestic living for generations across the U.S. Josephine Cochran is the original inventor of the first practical dishwasher and established the Garis-Cochran Dish-Washing Company in 1897 to manufacture the new, innovative device. After moving to Illinois from Ohio, Cochran built her prototype in a shed behind her house in Shelbyville. It could fit plates, cups and saucers inside a set of wire compartments and pumped hot soapy water onto the dishes, avoiding common issues like chipping and unwanted wear.

In 1886, Cochran secured a patent for her dishwasher design with the assistance of mechanic George Butters. Her design featured a motor, water wheel, a boiler to heat the water, and a rack system to hold the dishes neatly in place as they were sprayed with the soapy water. While Cochran’s dishwasher was the first to be commercialized, she initially sold them to hotels and restaurants to demonstrate its value in multiple settings. The large-size model of the dishwasher could wash and dry 240 dishes in two minutes. The success of her dishwasher enticed hospitals and colleges to purchase the machine for its effortless sanitizing effects.

Cochran’s dishwasher gained support and recognition from businesses, hospitals and schools, but it was not until the 1950s when dishwashers became popular and successful in American households. She was posthumously inducted into the Inventors Hall of Fame in 2006. Thanks to her persistence in seeing her invention succeed, Cochran formed a legacy for herself and changed the domestic experience for all Americans.
