The seven Jacuzzi brothers came from Italy to California in the early 1900s. All engineers, they designed a unique propeller known as the “Jacuzzi toothpick”— which revolutionized the young aircraft industry— and created an aircraft manufacturing company in Berkeley called “Jacuzzi Brothers”, which remained in business until 1976—though their product line changed dramatically over the years.
When Giocondo Jacuzzi died in 1921 in an airplane accident between Yosemite and San Francisco, their mother told her sons to work on something more down to earth, and so the Jacuzzi Brothers family firm adapted their propeller design to hydraulic pumps, and they quickly became one of the world leaders in the engineering and production of agricultural pumps used for wells and irrigation, This original Jacuzzi pump, one of their first designs, was installed by Charles Pagani (during Prohibition), soon after the Jacuzzi Brothers established their family business designing agricultural hydraulic pumps.
In 1948, Candido Jacuzzi used the company’s expertise in pumps to develop a submersible bathtub pump for his son, Kenneth, who had developed rheumatoid arthritis and suffered from chronic pain. He realized that their agricultural water pumps could be adapted to give his son soothing whirlpool treatments in the tub at home. This was the origin of the celebrated “Jacuzzi”. which led to an invention that remains an iconic fixture in American homes today.
