The Boiler Whisperer: Why the Man Who Warned Died First
Fear and inevitability: a man who held the highest steam-engineering license warned that an old boiler could not withstand the pressure, and within an hour an explosion equal to 660 pounds of dynamite annihilated a factory. Why was David Rockwell-the one who distrusted the machine-standing closest to it when it blew, and who failed to act on his warning?
In this episode, we tell what happened the morning of March twentieth, 1905 at the R. B. Grover Company and how a routine boiler swap turned into one of Brockton's deadliest industrial disasters. We follow Rockwell’s warnings, the decision to run a seventeen-foot, six-foot-diameter boiler built in 1890, and the unanswered question of why fifty-eight people never came home.
