Pat Olivieri

Pat Olivieri (1907-1974) was an American restaurateur. He is credited, along with his brother, Harry Olivieri, as the 1930 co-creator of the cheesesteak. The brothers opened Pat's King of Steaks in 1930, one of the best known purveyors of steak sandwiches in Philadelphia.

Olivieri died in 1974. His son Herbert Olivieri disputed ownership of the business with Harry Olivieri and his children. Harry's grandson Frank Jr. now runs the business.
