Boardwalk Empire Wiki

Stefano Magaddino is a minor character in Boardwalk Empire. Mentioned in the third season, and briefly appearing in the fifth season. He is a Castellammarese mafia don based in Buffalo, New York.



Magaddino was born in Castellammare del Golfo, Sicily and was a cousin of the later infamous Castellammarese crime boss, Joe Bonanno. He emigrated to the United States in 1909. After being arrested in 1921 in Avon, New Jersey, as a suspect in the murder of rival mobster "Don Petrino" Caiozzo, Magaddino moved to Niagara Falls, New York. There he combined a legal career as a mortician with one as a bootlegger, smuggling alcohol from Canada into Buffalo before branching out into other businesses, both legal and illegal. Magaddino was one of the most durable US crime bosses, his gripe over Upstate New York not being challenged until his arrest in 1968.

Season 3[]

Two New York City narcotics agents, Gaetano Caiozzo and Sam Moceri, meet with Lucky Luciano in June 1923 under the pretense of being members of Magaddino's crime family interested in buying heroin from him. Meyer Lansky advises Luciano to cancel the deal, noting that he doesn't know Magaddino, to which Luciano replies that he does. Luciano lies to Lansky saying that he will not make the deal but he does anyways and is arrested as a result. ("Two Imposters")

Season 5[]

After the death of Salvatore Maranzano, Magaddino comes to the meeting arranged by Lucky Luciano with the heads of the other families of New York. It is here where the Commission is formed as the governing body of the mafia, with Magaddino as the chairman for his family. ("Eldorado”)
