Triangle Shirtwaist Factory fire

Wikipedia - "The Triangle Shirtwaist Factory fire in New York City on March 25, 1911, was the deadliest industrial disaster in the history of the city of New York and resulted in the fourth highest loss of life from an industrial accident in U.S. history. It was also the second deadliest disaster in New York City – after the burning of the General Slocum on June 15, 1904 – until the destruction of the World Trade Center 90 years later. The fire caused the deaths of 146 garment workers, who died from the fire, smoke inhalation, or falling or jumping to their deaths. Most of the victims were recent Jewish and Italian immigrant women aged sixteen to twenty-three; of the victims whose ages are known, the oldest victim was Providenza Panno at 43, and the youngest were 14-year-olds Kate Leone and 'Sara' Rosaria Maltese."
