Gerlando "Jerre" Mangione (/mænˈdʒoʊni/ man-JOH-nee;[1] March 20, 1909 – August 16, 1998) was an American writer and scholar of the "Sicilian-American experience".

Mangione was “widely recognized by students of acculturation as a sensitive chronicler of the problems of negotiating the difficult passages between two cultures.”[3] He became famous upon the publication of his first book, Mount Allegro, a “classic autobiographical novel” about growing up in the Sicilian-American community of Rochester, New York.

"[5] Mangione claims that one of the reasons for writing "Mount Allegro" was his desire to show a positive image of Sicilians in America.

Up to that point he had "felt that the Sicilians in particular had been much maligned"[6] He also maintained that the book could be seen as a sort of personal Pilgrim's Progress in his relationship to the Sicilians of Rochester: a voyage "from being a kind of confused Italian-American living in two cultures, to observing them and writing about them objectively"[7] He wrote in depth about the Sicilian-American experience during the internment of Italian Americans during World War II.

[5] After publication of his final book, La Storia: Five Centuries of the Italian-American Experience, Mangione was honored by the Library of Congress with an exhibition of his works and papers.
