One hundred years ago this week, a fire at the Triangle Shirtwaist textile factory proved to be one of the most devastating industrial accidents in American history. The fire began on March 25, 1911, when textile scraps stored on the factory floor caught fire. Without adequate fire protection and fire escapes, 146 workers, mainly young immigrant women, died in the fire. Newspaper readers were shocked to read accounts of some workers who leapt, holding hands, from the ninth story to certain death in order escape the inferno. As is often the case, great tragedy proved to bring about great change.
