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".[7][8]
After mayonnaise, with an infusion of $50,[4] Dorsa branched out to waffle batter. When the waffle batter popularity exceeded the area to which it could be transported fresh, they developed a dry waffle mix that required only the addition of milk.[9][10] Dorsa's younger brothers, Sam,[11] and Anthony (Antonino),[12] handled sales and deliveries.[citation needed]
In 1938, they acquired the Santa Clara, California Garden City Potato Chip factory,[13] making Eggo potato chips. For the potato chip factory, Dorsa developed a continuous potato peeler.[14] Eggo expanded, to include salad dressings,[citation needed] noodles, and pretzels.[6]
Frank invented a fryer that wouldn't curl bacon.[15]
In 1953, Frank invented a carousel-motor-powered machine that would cook waffles and then freeze them.[15][6][9] Dorsa named the product Eggo frozen waffle.
In 1966, the Dorsas sold Eggo to Fearn Foods Inc.,[15][16] which was acquired by Kellogg's in 1970.[17]
Family
Frank Dorsa married Evelyn Mary Denevan in 1938. They had three sons, Frank Jr., Stanley and Richard.[18][19]
