Notes: National Carbon was formed in 1886 to market the first battery for consumer use and later became known for Eveready and Energizer batteries and lighting, including carbon elements for the lights used to film movies. The core business became the Energizer company.

The name "National Carbon Company" was used from 1941 to 1951. The National Carbon Company Building in San Francisco, CA, was renovated in 1983 and is now (2007) an event facility named Giftcenter Pavilion. It is listed on the Register of Historic Places.
