A brief sketch of the work of Matthew Fontaine Maury during the war, 1861-1865

In this concise, first‑hand portrait, the son of a renowned 19th‑century oceanographer recounts his father’s transition from charting the seas to defending a nation at war. Drawing on personal memories, letters and official papers, the narrative reveals how a brilliant mind, accustomed to mapping invisible currents, turned his attention to the desperate need for maritime protection when the Confederacy faced a superior Union navy.

The core of the story follows the daring development of underwater explosives—early torpedoes—that would become a cornerstone of naval strategy. From makeshift experiments in a Richmond kitchen to full‑scale production at local ironworks, the account shows how ingenuity, stubbornness and a willingness to defy convention allowed a handful of officers to turn the South’s rivers into lethal barriers. Listeners will gain insight into the blend of scientific curiosity and wartime urgency that propelled these inventions, setting the stage for modern naval warfare.
