Al Capone

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

Alphonse Gabriel “Al” Capone, son of 

Gabriele and Teresa, who had nine children, became an American gangster who led a Prohibition-era crime syndicate. He was forced out of Brooklyn by the White Hand Gang: was born in Brooklyn in 1899 and lived with his family on Navy Street where the notorious Italian Camorra gang was headquartered within the Irish community’s neighborhoods. He later moved to Park Slope and still a youngster, joined the Italian Five Points Juniors Gang. 

As a teenager, he started working for Frankie Yale, getting his infamous nickname 

"Scarface Al" by being slashed across the face by a gangster in Yale's Coney Island restaurant. Capone soon became the Italian crime world's hottest up-and-comer. According to multiple sources, Capone had caught the eye of the Irish White Hand Gang and made it onto their hit list. 

With a new wife and child and loads of opportunity in Johnny Torrio's Chicago, but knowing how gruesome and serious the White Handers were, Capone left Brooklyn. "It was common knowledge… that he had gone to Chicago because the Irish mob played too rough." ~Willie Sutton, famous Brooklyn bank robber

Other nicknames were

 King Alphonse, The Big Fella, Scarface, Snorky, Public Enemy No. 1, Big Al.
