author
b. 1846
A onetime professional gambler who reinvented himself as a reformer, he wrote vivid insider accounts of how gambling worked and why it could ruin lives. His best-known books mix memoir, exposé, and moral warning in a way that still feels surprisingly direct.

by John Philip Quinn
John Philip Quinn was an American writer and lecturer best known for books about gambling, especially Fools of Fortune; or, Gambling and Gamblers. Library and public-domain catalog records identify him as an author born in 1846, and his work presents itself as the testimony of someone writing from long personal experience inside the gambling world.
In Fools of Fortune, Quinn combines autobiography with a broad history of gambling and a detailed explanation of the tricks, schemes, and devices used by professional gamblers and confidence men. That blend of confession, warning, and practical detail helped make the book stand out from more distant moral essays on the subject.
Later editions and booksellers describe Quinn as a reformed gambler who turned to public speaking and anti-gambling advocacy. Even when some biographical details vary across sources, the overall picture is consistent: he wrote as an insider determined to expose the business of gambling rather than glamorize it.
