The Molasses Flood: When a City Buried Its Deadliest Secret | 2/12/26

In January 1919, Boston was struck by one of the strangest and deadliest industrial disasters in American history, when a massive molasses tank collapsed and sent a deadly wave through the city’s North End, killing 21 people.

In this At The Mic: Deep Dive episode, Keith Malinak is joined by historian and author Stephen Puleo, whose book Dark Tide remains the definitive account of the Boston Molasses Flood. Together, they explore the corporate negligence that led to the disaster, the human stories behind the tragedy, and the landmark civil trial that followed, one of the earliest cases to hold a corporation accountable for public harm. The discussion also explains how the flood permanently reshaped American building codes, safety standards, and the legal relationship between corporations and the public, revealing why this overlooked moment in history still matters today.
