Fredericka Mandelbaum took a boat from her home, the German state of Prussia, to New York City in 1850. She and her husband were very poor, but then she began her hustle! She took to a life of crime in 1857, after the collapse of the financial system in New York. She trained children to become thieves and pickpockets, according to Refinery 29. Her minions were so good, she bought a shop to resell the stolen goods! She was slick with it too, becoming friends with law enforcement. She became well-known in the Jewish community. In 1884, her house of cards fell down, as she was busted by a private detective. She jumped bail and lived the rest of her life out in Canada.
