Fredericka “Marm” Mandelbaum, nicknamed Queen of Fences, was a criminal working in the 13th Ward. She fenced stolen goods, knowingly buying stolen goods in order to later resell them for profit. She acted as a middleman between thieves and the eventual buyers of stolen goods. Over her career, she dealt with between $1 to 5 million in stolen goods. She was first recorded by the police in 1862 for peddling stolen merchandise door to door. In 1884, she was finally arrested through a sting operation, but escaped on bail. She lived in Canada until her death though she allegedly returned to New York in disguise, to attend the funeral of her daughter.
