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.
