The book presents the long-lost biography of Lionello Perera, principal banker, patron, and philanthropist of the Italian American community in New York at the inception of the twentieth century. Born and raised in Venice, Lionello Perera took over his uncle’s financial activity in Wall Street and developed the family business into a stronghold of the Italian American community. His remarkable career led him to become the Vice President of Bank of America in 1928 as an associate of California born Amadeo P. Giannini, while he also was instrumental to the political success of New York mayor Fiorello La Guardia. Recognised as a true founding father of the Italian American community of the East Coast, he supported welfare societies and public hospitals to foster the integration of Italian immigrants. A close friend of star conductor Arturo Toscanini, Lionello Perera and his wife Carolyn Allen Perera turned into influential music patrons for Italian and Jewish musicians. Their unique Art Deco house in the Upper East Side became an epicentre of the New York music world, showcasing the banker’s refined art collection that matched the taste of J. Pierpont Morgan and Samuel H. Kress. The book relies on unprecedented archival material rendering justice to the relevance Lionello Perera holds as a contributor to the political, social, and cultural integration of Italians in the USA. It offers an innovative perspective that considers the tight interrelation of Italian Americans of the East Coast with ongoing events in their country of origin. Lionello Perera’s life highlights the silent contribution of Italian Americans to change the US banking system and help the integration of Italian immigrants in their new country. Hence, the main audience are students and scholars interested in the history of immigration, banking history, Italian American culture as well as music studies and art history.
