25 March 1911
The Triangle Shirtwaist Company, occupying the top three floors of a ten-story building in New York City, was consumed by fire.
One hundred and forty-seven people, mostly women and young girls working in sweatshop conditions, lost their lives.
Approximately 50 died as they leapt from windows to the street; the others were burned or trampled to death as they desperately
attempted to escape through stairway exits locked as a precaution against "the interruption of work".
