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.[4] 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.
