Bertha Heyman, born around 1851, earned a notorious reputation in 19th-century America as one of the most daring con artists of her time. Known by nicknames like “Big Bertha” and the “Confidence Queen,” she operated with a boldness and cleverness that amazed even the most experienced lawmen. Detective Thomas F. Byrnes, a legendary New York police figure, once called her “one of the smartest confidence women in America”—a title she truly deserved for her brilliant manipulation and psychological insight. Unlike many con artists who relied on secrecy, Bertha's schemes were based on sheer audacity; she confidently entered high society, pretending to be fabulously wealthy, convincing wealthy men that she only needed temporary financial help.
Her scams were elaborate, and her victims were often educated, successful men who couldn’t imagine being outsmarted by a woman—especially one as physically imposing and socially commanding as Bertha. She didn’t just deceive them with tales of hidden fortunes or stranded inheritances; she charmed and disarmed them before emptying their pockets. One of the most remarkable parts of her criminal career was her ability to keep running cons even while behind bars. Bertha managed to swindle men out of thousands of dollars from prison, proving that her greatest weapon wasn’t freedom—it was her mind.
Bertha Heyman stood out in an era when women rarely appeared in the criminal spotlight, and never with the kind of infamy she held. While her crimes left a trail of broken trust and empty wallets, they also revealed the vanity and vulnerability of a society eager to believe in appearances. In many ways, she was a reflection of the Gilded Age—a time of glamor, greed, and illusion—where even the sharpest gentlemen could be brought down by the “Confidence Queen.”
