On the morning of April 16, 1947, residents of Texas City, a busy industrial port on the Gulf Coast of Texas, watched smoke rise from a cargo ship moored at the docks. Fires aboard ships were not uncommon, and many people gathered along the waterfront to observe the firefighters at work. Few suspected that within minutes they would witness one of the most devastating industrial disasters in American history.
At 9:12 a.m., the French cargo vessel SS Grandcamp exploded with tremendous force. The blast shattered buildings, ignited refineries, hurled pieces of steel across miles of countryside, and killed hundreds of people. By the time the catastrophe ended, at least 581 people were dead and more than 5,000 injured. It remains the deadliest industrial accident in United States history.
