Cassie Chadwick: The Woman Who Pretended to Be Andrew Carnegie's Daughter

In November 1904, a banker in Brookline, Massachusetts, sued a doctor's wife in Cleveland for $190,800. Within days the whole country learned her secret: Ohio's bankers had been lending her money for years because they believed she was the hidden daughter of Andrew Carnegie, the richest man in America. Carnegie's answer came in early December. He did not know her. Her name was Cassie Chadwick, born Elizabeth Bigley on an Ontario farm. This is the story of how a convicted forger became one of the most trusted borrowers in Ohio without ever proving a thing: a carriage ride to Carnegie's door, a sealed package of papers left with a Cleveland banker, a receipt that did the talking, and a small national bank in Oberlin that bet almost everything it had on one customer. The mechanism was not a lie. It was a secret, and a secret is the one thing a banker cannot check without giving it away.

QUESTION If she had walked into your bank with that receipt and that secret, would you have written the letter to Carnegie?
