The Triangle Shirtwaist Factory fire in the Greenwich Village neighborhood of Manhattan, New York City, on March 25, 1911, 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 the fire, smoke inhalation, or falling or jumping to their deaths. Most of the victims were recent Italian or Jewish immigrant women and girls aged 14 to 23.
The factory was located on the 8th, 9th, and 10th floors of the Asch Building, at 23–29 Washington Place, near Washington Square Park. The 1901 building still stands and is now known as the Brown Building, which is part of and owned by New York University (NYU). The building has been designated a National Historic Landmark and a New York City landmark.
