Author and historian Jay Feldman joins host Alan Lowe to discuss When the Mississippi Ran Backwards, his gripping account of the 1811–1812 New Madrid earthquakes. Alan and Feldman explore the quakes’ massive impact, including over 2,000 tremors felt across 1.5 million square miles, and the deep historical context behind them. He explains the ancient origins of the Reelfoot Rift, Tecumseh’s eerie quake prophecy, and how early steamboat travel intersected with disaster. Feldman also recounts a horrific crime against an enslaved teenager, exposed by the quakes, and touches on ongoing seismic risk today. He also discusses reflections from his new memoir. &nbsp;  Guest Bio Jay Feldman is an author, historian, and storyteller with a uniquely diverse background. Before turning to writing full-time, he worked as a musician and ran a music store specializing in vintage stringed instruments. He also founded Baseball for Peace, an organization promoting international understanding through sports, and has written for both television and the stage. Feldman is the author of Manufacturing Hysteria: A History of Scapegoating, Surveillance, and Secrecy in Modern America and When the Mississippi Ran Backwards: Empire, Intrigue, Murder, and the New Madrid Earthquakes, which explores one of the most powerful and overlooked natural disasters in U.S. history. &nbsp; Show Highlights  (4:32) When the earthquakes occurred and how many there were (9:23) The creation of the Reelfoot Rift and how it became the source of the quakes (12:38) What makes intraplate earthquakes different from other kinds (13:57) Why the Mississippi River ran backwards at the height of the quake (16:11) The creation of Reelfoot Lake (17:54) The legend of Tecumseh’s prophecy about the earthquakes (21:55) How the Roosevelt family was involved with the event (27:55) The crime that was revealed in the wreckage of the earthquakes (32:44) Seismic activity in the area today  &nbsp; Links Referenced  Manufacturing Hysteria: A History of Scapegoating, Surveillance, and Secrecy in Modern America:  When the Mississippi Ran Backwards: Empire, Intrigue, Murder, and the New Madrid Earthquakes:

Railroads have shaped America’s growth, technology, and daily life for nearly two centuries. In this episode of AMSEcast, Alan talks with Dr. Albert Churella of Kennesaw State University about how innovations such as the automatic knuckle coupler, Westinghouse’s air brake, and the move from steam to diesel transformed safety and efficiency. Dr. Churella explains how signaling, centralized traffic control, and GPS-based Positive Train Control modernized operations. While U.S. passenger service lags Europe, its freight rail system leads the world in ton-miles, fuel efficiency, and low emissions. Albert also previews his forthcoming book on Conrail, reflecting on the railroad industry’s resilience, its economic impact, and its enduring relevance today. &nbsp; About Dr. Albert Churella  Dr. Albert Churella is a leading scholar of transportation history and policy with a particular focus on railroads. He earned both his MA and PhD from The Ohio State University and now serves as a professor at Kennesaw State University. Albert’s research explores how railroads shaped American economic growth, technology, and public policy, linking the past to today’s transportation challenges. His work combines rigorous scholarship with a clear, engaging style that reaches beyond academic audiences. In addition to his extensive publications, Albert is widely regarded as an expert who makes the complex history of railroads accessible and relevant to modern readers. &nbsp; Show Highlights  (1:40) When the first train operated in the United States (14:13) America’s addition of the air brake and the automatic coupler (28:12) When track signals came into use (40:05) Are trains high-tech now? (45:04) The transition from steam to diesel and where the advancement was developed (58:29) Why railways are still important in the US (1:02:52) What Dr. Albert Churella is working on now  &nbsp; Links Referenced  The Pennsylvania Railroad three-volume series:
