Source-derived summary

The Dubilier Condenser Company was the earliest commercial manufacturer of electronic capacitors (formerly known as condensers) which were widely used in early AM radio receivers (wireless sets). The company was founded in New York in 1920 by William Dubilier.

History

The company was founded in New York in 1920 by William Dubilier, who was responsible for many early developments in the field of electronics and radio, including the use of mica in capacitors. Dubilier was a name commonly found on capacitors in early wireless sets in Britain alongside TCC, Wima and others.

In 1923, Harry Houck joined Dubilier, later to become chief engineer.

Dubilier Condenser merged into Cornell-Dubilier in 1933.

In February, 1927, William Dubilier stepped down as president, naming Fred Williams as President and director of sales.

The former Cornell-Dubilier manufacturing site in South Plainfield, NJ became the subject of remediation under the U.S. Environmental Protection Agency’s Superfund program. According to the EPA, manufacturing activities at the facility (1936–1962) resulted in releases of polychlorinated biphenyls (PCBs) and chlorinated volatile organic compounds (VOCs), primarily trichloroethylene (TCE), contaminating soil, sediment, and groundwater. PCBs were used in capacitors manufactured at the site.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american manufacturer of capacitors. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 15, 2026. The linked authority identifier is Q5310749. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1920, 1923, 1933 and 1927.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
