September 10, 1931 is one of the most important dates in American organised crime history. On that day, Salvatore Maranzano — who had declared himself boss of all bosses after winning the Castellammarese War — was shot and stabbed in his Park Avenue office. The killing was organised by Lucky Luciano, who used the occasion to abolish the position of supreme boss entirely and establish the Commission — the ruling body of the American Mafia — in its place. The modern Mafia was born on this day.
September 26, 1902 was the birthday of Albert Anastasia — the Mad Hatter, founder of Murder Incorporated and one of the most feared men in mob history. Born in Calabria and arriving in New York as a teenager, Anastasia would go on to order or commit dozens of murders before being shot dead in his own barber’s chair in 1957.
September 3, 1929 was the birthday of James “Whitey” Bulger — the Boston gangster who ran the Winter Hill Gang while secretly serving as an FBI informant, an arrangement that allowed him to eliminate rivals while staying one step ahead of law enforcement for decades. He was a fugitive for 16 years after his 1994 indictment, finally captured in 2011. He was killed in prison in 2018.
September 21, 1926 saw one of the most audacious attacks in Prohibition-era Chicago. Hymie Weiss led a convoy of cars that fired over 1,000 rounds into Al Capone’s Hawthorne Hotel headquarters in Cicero. Capone survived by throwing himself to the floor. The attack accelerated the gang war that would culminate in the St Valentine’s Day Massacre.
