Jacuzzi is a corporation that today produces toilets, whirlpool bathtubs, and hot tub spas. Its first product was a portable hydrotherapy unit that sat in the bath. Later, the jet that was used in the portable unit was incorporated into the wall of a swimming pool and later adapted to the wall of a fiberglass bath tub. JACUZZI is a federally registered trademark of Jacuzzi Inc. as of September 5, 1978.
Founded in 1915 by seven Italian brothers from Casarsa della Delizia in Northern Italy, led by Giocondo Jacuzzi, Jacuzzi and Brothers made wooden propellers under military contracts, based at 2043 San Pablo Avenue, Berkeley, California. In 1920, the brothers also dabbled briefly with aircraft design and manufacture, with a single-seat monoplane and a seven-seat cabin monoplane. Both aircraft were noted for their use of laminated wood products for fuselage manufacture, but were essentially unsuccessful, with only one of each type being built. In 1921, Giocondo Jacuzzi, a pilot, and two company employees were killed when one of their planes crashed in Modesto. By 1923, the company was styled as Jacuzzi Bros Propellers, with headquarters at 1450 San Pablo Ave.
The company survived to become a whirlpool and bubble bath manufacturer, with the name Jacuzzi eventually becoming synonymous with the bath products regardless of manufacturer.
