Following her marriage in 1897, Chadwick began her largest, most successful con game: that of establishing herself as
Andrew Carnegie's daughter. During a visit to
New York City, she asked one of her husband's acquaintances, a
lawyer named Dillon, to take her to Carnegie's home. In reality, Chadwick visited Carnegie's housekeeper while ostensibly trying to check credentials. When Chadwick came back, she dropped a paper. Dillon took it up and noticed it was a
promissory note for $2 million with Carnegie's signature. When Dillon promised to keep Chadwick's secret, she "revealed" that she was Carnegie's
illegitimate child. Carnegie was supposedly so wracked with guilt that he showered huge amounts of money on her. Chadwick also claimed that there was $7 million in promissory notes tucked away in her Cleveland home, and she was to inherit $400 million upon Carnegie's death. Dillon arranged a
safe deposit box for her document. The information leaked to the financial markets in northern Ohio, and
banks began to offer their services to Chadwick. For the next eight years, she used her fake background to obtain loans that eventually totaled around $2 million ($ in today's currency). Chadwick relied on the assumption that no one would ask Carnegie about an illegitimate daughter for fear of embarrassing him. Since the loans also came with
usurious interest rates, the bankers would not admit to granting them. Chadwick forged
securities in Carnegie's name for further proof. Bankers assumed that Carnegie would vouch for any debts and that they would be fully repaid once Carnegie died. Chadwick carried out a lavish lifestyle as a result of her con. She bought diamond necklaces, enough clothes to fill 30 closets, and a gold organ. She became known as "the Queen of Ohio." She claimed to give money to the poor and to the suffrage movement. In November 1904, Chadwick received a $190,000 loan from Herbert B. Newton, a
Brookline, Massachusetts banker. It was also discovered that a number of securities being held for her in various banks were worthless. When Carnegie was later asked about her, through a spokesman he denied ever knowing her. Carnegie further stated he had not signed a promissory note in more than 30 years. ==Second U.S. fraud trial==
