Kingsland Explosion

The Kingsland factory was a munitions plant operated by the Canadian Car and Foundry Company in Kearny that manufactured artillery shells for Russia and Britain during World War I. The facility spread across multiple industrial buildings in northern New Jersey, close to Manhattan.

A series of explosions occurred on January 11, 1917, at the factory that discharged around 500,000 shells over several hours. This event was one of the largest industrial accidents of the war period and raised concerns about the dangers of munitions production.

Switchboard operator Tessie McNamara's quick warning to her coworkers became a symbol of courage and responsibility during wartime industrial work. Her actions showed how people at the facility looked out for one another in dangerous moments.

The site can be visited today and is marked by a commemorative plaque and a remaining smokestack from the original location. It is easy to reach and offers an accessible view of this important historical location.

A man named Theodore Wozniak, suspected of deliberately starting the fire, disappeared after the disaster. The circumstances of his disappearance and possible connections to Germany remained unclear for many years and captured public attention.
