The Triangle Shirtwaist Factory fire in the Greenwich Village neighborhood of Manhattan, New York City, on Saturday, 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; of the victims whose ages are known, the oldest victim was 43-year-old Providenza Panno, and the youngest were 14-year-olds Kate Leone and Rosaria "Sara" Maltese.The factory was located on the 8th, 9th, and 10th floors of the Asch Building, which had been built in 1901. Later renamed the "Brown Building", it still stands at 23–29 Washington Place near Washington Square Park, on the New York University (NYU) campus. The building has been designated a National Historic Landmark and a New York City landmark.Because the doors to the stairwells and exits were locked – a common practice at the time to prevent workers from taking unauthorized breaks and to reduce theft – many of the workers could not escape from the burning building and jumped from the high windows. The fire led to legislation requiring improved factory safety standards and helped spur the growth of the International Ladies' Garment Workers' Union (ILGWU), which fought for better working conditions for sweatshop workers.
