The Triangle Shirtwaist Factory fire occurred in the Greenwich Village neighborhood of Manhattan, a borough of New York City, on Saturday, March 25, 1911. The fire was the deadliest industrial disaster in the history of the city, and one of the deadliest in U.S. history. The fire caused the deaths of 146 garment workers—123 women and girls and 23 men—who died from either the fire, smoke inhalation, or falling or jumping to their deaths. Most of the victims were recent Italian or Jewish immigrants aged 14 to 23.
