Botany and Betrayal:
The Scientist Turned Spy

March 12, 2025

11 a.m. to 12 p.m. | Mertz Library

A book cover reading "The Scientist Turned Spy," in blue, orange, and whiteAndré Michaux was one of the most accomplished scientific explorers of North America before Lewis and Clark. His explorations took him from the Bahamas to Hudson Bay, and it is likely that no contemporary of his had seen as much of the continent. However, there is more to his story.

During his decade-long American sojourn, Michaux found himself thrust into the middle of a vast international conspiracy. In 1793, the revolutionary French government conscripted him into its service as a secret agent and tasked him with organizing American frontiersmen to attack Spanish-controlled New Orleans, seize control of Louisiana, and establish an independent republic in the American West.

Join author and incoming CEO of the American Philosophical Society (APS) Patrick Spero as he draws on sources buried in the vault of the APS that shed new light on an incipient American political climate which fostered reckless diplomatic ventures under the guise of scientific exploration, revealing the air of uncertainty and opportunity that pervaded the early republic.
