How many women died in the Triangle Waist Company fire in New York City?

At least 146 women, mainly young immigrants, died in the sweatshop fire in the Triangle Waist Company that occurred on April 20, 1911.

The sprinkler system was inadequate, the 500 female workers stood back-to-back on the crowded work floors, and the fire doors were kept locked to prevent theft.

The company owners were later acquitted of manslaughter charges.
