Biography/Administrative History
The DuPont corporation and Lafkin & Rand Powder Company incorporated the Hercules Powder Company in 1882 to manufacture Hercules
powder (a special form of dynamite). The company was dissolved in DuPont in 1904, but was newly created in 1912. In 1966,
the company changed its name to Hercules, Inc. and was sold to the Ashland Corporation in 2008.
Scope and Content of Collection
Many large format and panoramic photographs of the Hercules Powder Company located on San Pablo Bay between Richmond and Martinez.
Includes photos of marine equipment such as kelp cutters, lighters, and tugs. Kelp was a raw material used in dynamite.
Most of the photos in this album are of the vessels and equipment used for kelp harvesting and processing. The end product
was potash that was used at the plant and shipped to other manufacturers.
