In the spring of 1902, a woman calling herself Cassie L. Chadwick made her way from Cleveland to New York City and took up position in the lobby of the Holland House, a luxury hotel at 30th Street and Fifth Avenue. She was waiting for James Dylan, a lawyer and friend of her husband. When she spotted him, she approached as if by chance, feigned surprise at the encounter, and asked whether he might escort her to her father’s house.

Dylan obliged, hailing an open carriage. Cassie directed the driver to two East 91st Street, the Manhattan mansion of steel magnate Andrew Carnegie. Dylan was struck silent when he realized whose home it was. Cassie went inside alone, told the housekeeper she was considering hiring a former Carnegie maid, received confirmation that no such person had ever worked there, and left with a large brown envelope concealed under her coat.

When Dylan asked who her father was, she put a finger to her lips. She claimed to be Carnegie’s illegitimate daughter, and said the envelope contained promissory notes and securities worth five million dollars, gifts from a guilt-ridden father, with a vast inheritance to come upon his death. She swore Dylan to secrecy. The secret, of course, was too good to keep.

Cassie Chadwick was not Carnegie’s daughter. She had never met him. She was not even Cassie Chadwick. She was Elizabeth Biggley, born in October 1857 on a small farm in Ontario, Canada, the fifth of eight children.

As a girl, she lost hearing in one ear and developed a speech impediment that made her speak rarely and carefully. Her classmates thought her peculiar. She sat in silence for hours, and her sister Alice said Betty often seemed to be in a trance, as if hypnotized, unaware of anything outside her own mind. Sometimes Alice noticed her practicing family members’ signatures, writing the names over and over.

At thirteen, Betty devised her first scheme. She forged a letter announcing that an uncle had died and left her money. The notification looked authentic enough to fool a local bank, which issued checks against accounts that did not exist. She was arrested within months and warned not to do it again.

She did not stop. In 1879, at twenty-two, she launched what would become her signature scam. Using expensive letterhead and a fictitious attorney’s name, she notified herself that a philanthropist had died and left her an inheritance of fifteen thousand dollars. She had business cards printed resembling the calling cards of the social elite.

Hers read, “Miss Biggley, Heiress to $15,000. ” Then she entered shops, bought expensive items, and wrote checks for more than the price, asking merchants for the difference in cash. When questioned, she produced the card. Why would anyone doubt a woman who announced her inheritance so plainly?

It worked every time. She moved to Cleveland to live with her married sister Alice, then took out a bank loan using her sister’s household furnishings as collateral. When Alice’s husband discovered the ruse, he threw her out. She found lodging elsewhere and met Dr.

Wallace S. Springsteen, who was immediately captivated. Betty was plain, with a tight unsmiling mouth and dull brown hair, but her eyes had an intensity that one newspaper would later call hypnotic, and her lisp seemed to give her words a quiet truth. They married before a justice of the peace in December 1883.

Within days, furious merchants appeared at the door demanding repayment. The doctor paid off her debts, fearing his own credit was at risk. The marriage lasted twelve days. Betty then became Marie Rosa, moving through boarding houses and refining her methods.

In Erie, Pennsylvania, she claimed to be the niece of Civil War General William Tecumseh Sherman. She faked a dramatic illness, drawing blood from her gums to simulate a hemorrhage. Sympathetic citizens gave her money to return to Cleveland. When they later asked for repayment, they received letters mourning Marie’s death, supposedly just two weeks after her departure, complete with a eulogy written by Betty herself.

As Madame Rosa, she claimed clairvoyant powers and entangled herself with two clients. A brief marriage to a Trumbull County farmer dissolved quickly. A second, to businessman C. L.

Hoover, produced a son, Emil, whom she sent to Canada to be raised by her family. When Hoover died in 1888, Betty inherited fifty thousand dollars, a fortune that financed yet another transformation. In Toledo, as Madame Lydia Dair, she persuaded a well-regarded local man named Joseph Lamb to cash forged promissory notes for her, totaling forty thousand dollars. The scheme unraveled.

Lamb was exonerated. Betty was convicted of forgery and sentenced to nine and a half years in prison. Even behind bars, her persona as a seer held. She predicted the warden would lose five thousand dollars and die of cancer, and both came to pass.

She wrote letters to the parole board expressing contrition and promising reform, and Governor William McKinley, the future president, granted her early release after just three and a half years. Back in Cleveland, she became Cassie E. Hoover and married Dr. Leroy S.

Chadwick, a wealthy widower and a scion of one of the city’s founding families. The marriage took hold among the city’s elite, who knew nothing of her past. She played the role of the doctor’s devoted wife, and her alleged therapeutic touch for his rheumatic back sealed the match. As Cassie Chadwick, she set out to impress her prominent neighbors, among them relations of John D.

Rockefeller, U. S. Senator Marcus Hanna, and John Hay, who had been one of Abraham Lincoln’s private secretaries. She bought whatever struck her fancy and never asked the price.

She replaced the doctor’s gloomy furnishings with bright pieces, bought a nine-thousand-dollar pipe organ, a musical chair, a chest of eight trays of diamonds and pearls inventoried at ninety-eight thousand dollars, and a forty-thousand-dollar rope of pearls. At Christmas in 1903, the year after James Dylan told all of Cleveland about her connection to Carnegie, she bought eight pianos at once and gave them away as gifts. When her husband objected to her spending, she borrowed against her future inheritance. Her financial associates never believed Mrs.

Chadwick capable of an elaborate paper trail of lies. She took out large loans from Ohio Citizens Bank, Cleveland’s Wade Park Banking Company, and New York’s Lincoln National Bank, and smaller sums, never less than ten thousand dollars, from a dozen other banks. She repaid one loan with money from the next. She used Wade Park Bank as her base and entrusted it with counterfeit promissory notes from Carnegie.

She convinced Charles Beckwith, president of Citizens National Bank, to lend her two hundred forty thousand dollars, plus an additional one hundred thousand from his personal account. A Pittsburgh steel mogul, likely an acquaintance of Carnegie’s, gave her eight hundred thousand. Through the Euclid Avenue Baptist Church, she connected with Herbert Newton, an investment banker in Boston. He lent her one hundred four thousand dollars and was pleased when she signed a promissory note for one hundred nine thousand eight hundred without questioning the exorbitant interest.

By November 1904, Newton realized Cassie had no intention of repaying the loans and filed suit in federal court in Cleveland. The suit asked that Ira Reynolds, secretary and treasurer of Wade Park Bank, who had himself lent most of his personal fortune to Cassie, continue to hold the promissory notes from her father. Cassie denied all charges and denied any relationship with Andrew Carnegie. “It has been said repeatedly that I had asserted that Andrew Carnegie was my father,” she said.

“I deny that and I deny it absolutely. ”

Beckwith visited her in jail. Although her frauds had collapsed his bank and destroyed his personal wealth, he studied her through the bars of her cell. “You’ve ruined me,” he said.

“But I’m not so sure yet you are a fraud. ”

The full extent of her spoils remains unknown. Some historians believe many victims chose not to come forward. The most commonly cited figure is six hundred thirty-three thousand dollars, roughly sixteen and a half million in today’s money.

In March 1905, Cassie Chadwick was found guilty of conspiracy to defraud a national bank and sentenced to ten years in the penitentiary. Carnegie himself attended the trial and later examined the infamous promissory notes. “If anybody had seen this paper and then really believed that I had drawn it up and signed it, I could hardly have been flattered,” he said, pointing out errors in spelling and punctuation. “Why, I have not signed a note in the last 30 years.

” The whole scandal could have been avoided, he added, if anyone had bothered to ask him. Elizabeth Biggley, who had been Marie Rosa, Madame Lydia Dair, and Cassie Chadwick, ended her run as the greatest conwoman of the Gilded Age, her elaborate fictions finally undone by the simple fact that no one had ever checked.
