Ensign-Bickford Company
The Ensign-Bickford Company was started in 1836 in Connecticut, USA as a manufacturer of William Bickford 's safety fuse for use in mining. Safety fuse was a great advance in mining technology over the practice of filling holes with black powder. The next step in mining technology was detonating cord. Ensign-Bickford and other companies developed different versions of detonating cord. Ensign-Bickford's "Primacord" or "primercord" became the functional generic name for detonating cord in North America. In 2003 Ensign-Bickford sold the trademarks and processes to Dyno Nobel Inc of Norway.
