Broken dishes so much, woman invented dishwasher

In June 1893, Chicago (USA) became bustling. More than 27 million people came to attend the event: the World's Columbian Exposition, also known as the World's Fair. Here, the invention that attracted the most attention was the Garis-Cochran dishwasher . This was the only invention created by a woman at that time. Photo: US Patent and Trademark Office.

More than 200 dirty dishes were loaded onto the racks of the Garis-Cochran dishwasher , pushed into a container lined with pulleys and gears. Two minutes later, the clean dishes were brought out. The machine was not just for show; many restaurants at the fair used it to wash tens of thousands of dishes every day. Photo: US Patent and Trademark Office.

The Garis-Cochran dishwasher also received an award for its “good mechanical construction, durability, and suitability for the job.” This was a breakthrough moment for inventor Josephine Garis Cochran, who would revolutionize the way household appliances are developed today.

Cochran was born in Ashtabula County, Ohio, in March 1839. She grew up in a family of life-changing inventions, including her great-grandfather who received one of the first patents for a steamboat. Her father was a civil engineer who operated factories in Ohio and Indiana. Photo: Museum of Science and Industry, Chicago/Getty Images Museum of Science and Industry, Chicago.

After her mother died, Mrs. Cochran moved to live with her sister in Illinois. There she met William Cochran. In 1858, Mrs. Cochran, at age 19, married William, who was nine years her senior. As the wife of a successful merchant, she lived a comfortable life. Photo: US Patent and Trademark Office.

The Cochrans moved into a large house in Shelbyville, Illinois, with several servants. They socialized with neighbors and used her family’s 17th-century Chinese porcelain set to entertain guests. Photo: Chicago History Museum/Getty Images Chicago History Museum.

So Cochran devoted her efforts to developing the dishwasher. She later hired mechanic George Butters to help build a prototype from scratch. Photo: messynessychic.

Just days after Christmas in 1886, Mrs. Cochran received a patent for her dishwasher. While the machine was not the first of its kind, her design used water pressure instead of a scrubbing device to clean dishes. It was a revolutionary idea that modern dishwashers still use. She hoped that the Garis-Cochran dishwasher would help ease the burden of cleaning for women. Photo: messynessychic.

Thanks to her success at the 1983 Chicago World's Fair, Ms. Cochran received many orders for the Garis-Cochran dishwasher. Not only hotels and restaurants, many hospitals also bought and used her invention. Photo: messynessychic.
