Founded in 1915 by seven brothers, 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.
