Who invented the dishwasher? The fascinating history

Share via

While we often take modern conveniences for granted, the origins of these innovations are rooted in ingenious human creativity. One such trailblazing invention is the dishwasher, a household staple that often spares us from the tedium of hand-washing dishes. Who was behind this time-saving appliance? Let’s find out!

Who invented the dishwasher?

The concept of the dishwasher wasn’t born overnight. In fact, it took the innovative spirit of many people through the centuries. But we can attribute the first commercially successful dishwasher to Josephine Garis Cochran, an enterprising woman from Shelbyville, Illinois, who ushered in a new era of domestic convenience.

Josephine, a socialite who frequently entertained, was driven by a desire to protect her fine heirloom china, which would often chip during hand-washing by her kitchen staff. She started doing the dishes herself but soon decided there had to be a better way.

“If nobody else is going to invent a dishwashing machine, I’ll do it myself” - Josephine Cochran

Cochran’s design, which included water jets and wire compartments to hold the dishes safely in place, would eventually become the first commercially successful dishwasher.

Earlier dishwashers

While Cochran is lauded as the inventor of the dishwasher, earlier mechanical versions of this appliance date further back to the 1800s.

The first dishwasher

In the 1850s, Joel Houghton patented the first hand-powered dishwasher in the United States. However, it was Josephine Cochran’s water-pressure design that made it commercially viable, paving the way for modern dishwashers. She even showcased her invention at the Chicago World's Fair in 1893 and received orders from restaurants and hotels eager to save time and labor.

Evolution of the dishwasher

Over the years, dishwashers have evolved with technological advancements, making them more efficient, user-friendly, and energy-efficient. In 1924, William Howard Livens invented a portable dishwasher that could be hooked up to any tap. Then in the 1950s, dishwashers were introduced in homes as a luxury item, and by the 1970s, they became more affordable for the average household.

Embracing modern conveniences

Whether she knew it or not, Josephine Cochran’s ingenuity and inspiration could also be viewed as rooted in feminism. She was famously quoted as saying, “When it comes to buying something for the kitchen that costs $75 or $100, a woman begins at once to figure out all the other things she could do with the money. She hates dishwashing—what woman does not?—but she has not learned to think of her time and comfort as worth money. Besides, she isn’t the deciding factor when it comes to spending comparatively large sums of money for the house.”

Looking back on Josephine Cochran's pioneering contribution, it becomes evident that her forward-thinking approach transcended her time. Her invention not only alleviated the burden of manual dishwashing for those who could afford it, but it also paved the way for future innovations in home appliances that would eventually become available to a much broader customer base. The impact of her ingenuity continues to resonate in households worldwide, embodying the essence of progress and practicality.
