Cassie Chadwick
con artist (1857–1907)
Cassie L. Chadwick (10 October 1857 – 10 October 1907) was the most well-known pseudonym used by Canadian con artist Elizabeth Bigley, who defrauded several American banks out of millions of dollars during the late 1800s and early 1900s by claiming to be an illegitimate daughter and heiress of the Scottish-American industrialist Andrew Carnegie. Newspaper accounts of the time described her as one of the greatest con artists in American history. She pulled off the scam in the Gilded Age of American history, during which time women were not allowed to vote or get loans from the banks, leading some historians to refer to her bank heist as one of the greatest in American history.
Early life
Cassie Chadwick was born Elizabeth Bigley on October 10, 1857, in Appin, Canada West. She was the third daughter in a family of two boys and six girls born to Daniel and Mary Ann Bigley. Daniel was a railroad section hand. Three years later, the Bigleys moved to a small farm near Eastwood, Canada West. At sixteen, Betsy ran away from home, but was apprehended by police after attempting to obtain a $250 promissory note from a prosperous farmer. In 1878, Betsy was arrested for attempting to borrow money on a stolen pocket watch. Her father settled with the victim.
This brief starts where responsible research should: with the source description of “Cassie Chadwick” as con artist (1857–1907). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as con artist (1857–1907). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated May 28, 2026. The linked authority identifier is Q1048357. VIAF identifies the subject as 61128108. The Library of Congress control number is no95024341. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1857, 1907 and 1878.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
