A Lost Chapter in the History of the Steamboat

In the spring of 1828 a freshly minted lawyer works out of a cramped office in Baltimore’s Athenæum building, when an imposing stranger bearing a rich Irish lilt steps through the door. The visitor, John Devereux Delacy, reminds the young attorney of a childhood encounter and immediately presents a startling commission: a parchment patent signed by James Madison and James Monroe granting exclusive rights to a pioneering steam‑propulsion system. Delacy’s proposal is simple yet audacious—file a suit against every steamboat owner in the United States, starting with the notorious Billy McDonald, and secure a fortune for both men.

The document details an early design of paddle wheels, adjustable floats, and boiler arrangements that promised to revolutionize river travel. As the lawyer pores over the technical language, he senses the weight of history and the promise of wealth, but also the daunting task of confronting a whole industry. Listeners are drawn into a world of legal maneuvering, 19th‑century innovation, and a mystery that could reshape America’s waterways.
