The Jewish Mafia.
Ugh.
There have been many ties between the Sicilian mafia and Jewish, Irish, and other mobsters. Arnold Rothstein was more of a gambler than a true mobster. He profited if not directly fixed the 1919 World Series. He worked with mobs and hired associates that were not Jewish including a pre-famous Legs Diamond.
The Beer Baron of the Bronx, Dutch Shultz, was not Dutch and his real name was Arthur Flegenheimer. He was a Jew and worked with all kinds but he met his end surrounded by his own kind at the Palace Chop House in Newark. On that day he and Abbadabba Berman, Lulu Rosenkrantz, and Abe Landau were shot up by two assassins. None of the Shultz party died at the scene but all four died from their wounds over the next 30 hours. Shultz sought and received last rites as a Catholic but was of Jewish heritage. Some of his death bed ramblings are often quoted including, “Mother is the best bet and don’t let Satan draw you too fast.”
Purple gang.
Myer Lansky?
