One of the Bay Area’s first business booms was the rapid growth of explosives manufacturing following the Gold Rush. The power of nitroglycerine and later dynamite enabled industrial-scale mining, continent-spanning railroads, and a total reshaping of California’s landscape. For many decades, the small Contra Costa town Hercules produced millions of tons of explosive chemicals that were used to move mountains, build cities, and wage wars. This episode features an interview with Stephen Lawton, a longtime resident of Hercules who
co-authored a book all about his town’s earth-shattering history.

“Joe Scarsella, October 1929. Highly unstable nitroglycerine was moved in a cart with two compartments. One worker explained, ‘We called ’em angel buggies cause one sharp bump and that’s what you’d be.’ This spot is now the waterfront residential neighborhood of Hercules.” (Caption from Hercules book, photo courtesy of Ashland, Inc.)
Accidental explosions were a major reason why explosives manufacturing migrated from San Francisco and Alameda Counties to a more remote region of northwest Contra Costa County. The others killed in the blast besides the “four white men” were likely Chinese laborers. (Photo courtesy of Hercules Historical Society)
