Frank Joseph Dorsa (August 18, 1907 – January 17, 1996)[1][2] was an American food machinery inventor, best known for the Eggo frozen waffle.
[4] His first job after graduation was as a machinist at a small company, later bought by Los Gatos-founded FMC Corporation.
In 1932,[5][6] the Dorsa brothers developed a mayonnaise, noted for its use of "100 percent fresh ranch eggs" and "triple refined vegetable oil".
[9][10] Dorsa's younger brothers, Sam,[11] and Anthony (Antonino),[12] handled sales and deliveries.
[14] Eggo expanded, to include salad dressings,[citation needed] noodles, and pretzels.
