Josephine Cochrane

Early Life and Education

Josephine Cochrane (March 8, 1839 – August 14, 1913) was an American inventor and entrepreneur, best known as the inventor of the first commercially successful automatic dishwasher. Born in Ashtabula County, Ohio, Cochrane grew up in a family of inventors and engineers which influenced her creative tendencies [1]. Despite having no formal education in engineering or science, she possessed a keen intellect and a knack for innovation.

Career and Research

Cochrane frequently hosted dinner parties where she used fine china. However, she grew increasingly frustrated with the damage her china sustained from being handwashed by servants. Determined to find a solution, she sought to create a machine that could wash dishes more efficiently while minimizing breakage.

In 1883, Josephine Cochrane's life took a  turn when her husband, who battled alcoholism, passed away -- leaving her with only $1,500 and in significant debt. This sudden loss forced Cochrane to confront the reality of her financial struggles and added urgency to turn her invention of a viable dishwashing machine into a commercial success [2].

Cochrane's research involved studying existing dishwashing methods and experimenting with various designs and mechanisms. Drawing on her family's background in engineering and her own natural curiosity, she developed a prototype for an automatic dishwasher that used water pressure to clean dishes [2] Cochrane's design was innovative for its time, eliminating need for manual scrubbing and offered a more efficient alternative to traditional handwashing methods.

Innovation

Despite facing skepticism and challenges from potential investors, Cochrane was determined in bringing her invention to market. She continued to refine her design and eventually received a patent for her automatic dishwasher in 1886 and founded her own company (Cochrane Manufacturing Company) to manufacture and sell her dishwashers alongside George Butters, a mechanic who assisted her in the construction of the dishwasher. 

Facing challenges with selling her automatic dishwasher to homemakers due to their limited income and lack of interest, Cochrane shifted her focus to market to  hotels [3]. She recognized that hotels had a need for efficient dishwashing solutions and were better positioned financially to invest in such technology and targeted the specific market.

Recognition & Conclusion 

Continuously refining her invention, she earned a second patent  in 1917, showcasing her ongoing commitment to improvement. The culmination of her efforts resulted in the establishment of the Crescent Dishwashing Company which was acquired by KitchenAid appliances before becoming part of Whirlpool Corporation. 

Throughout her life, Cochrane demonstrated remarkable entrepreneurial spirit, founding her own company to manufacture and sell her dishwashers. Despite initial skepticism from potential investors, her invention gained recognition and eventually became a staple in households and commercial establishments worldwide.

Josephine Cochrane's legacy has grown significantly in the years since. In 2006, she was inducted into the National Inventors Hall of Fame as one of the great women inventors of the early Industrial Era [4].

Today, Josephine Cochrane is remembered as a pioneering figure in the history of domestic technology, whose innovation profoundly impacted everyday life and has served as an anchor for the well-known brand KitchenAid. Her legacy endures as a testament to the power perseverance in overcoming challenges and bringing about transformative change.
