In 19th century Delaware, workers at the DuPont Black Powder Mills had a phrase for their dead colleagues: "He went across the creek." It was a gentle way to describe something horrific—being literally blown to atoms in an explosion. Sometimes all that remained was a burning rag, a piece of clothing still on fire from the chemical dust that killed them.

Between 1802 and 1921, there were 290 explosions at the DuPont mills just outside Wilmington, Delaware. The buildings were deliberately designed with only three walls and weak roofs to channel blast forces across the Brandywine Creek. Despite the constant danger, there was always a line of men ready to work. The pay was good, the housing was free, and the DuPont family took care of widows. But the risk was real—235 people died making black powder on those grounds.

Author and Hagley Museum tour guide Dick Templeton joins us to discuss his book "Across the Creek" and reveal the forgotten culture of Delaware's powdermen: their gallows humor, their three-sided factories, and the tavern called the Blazing Rag where they drank after work.
