In one of the darkest moments of America’s industrial history,
the Triangle Shirtwaist Company factory in New York City
burned, killing 146 workers, on March 25, 1911. The tragedy
led to the development of a series of laws and regulations
that better protected the safety of factory workers.     

The Triangle factory, owned by Max Blanck and Isaac Harris, 
It was a sweatshop in every sense of the word: a cramped
space lined with workstations and packed with immigrant
workers, mostly teenage women who did not speak English.
