Teaching hard history
- Never use role-play or simulations of slavery, violence, or other atrocities. Ask students to analyze the testimony and documented choices of real people instead.
- Pair the voices of the people who did the work (enslaved people, children, strikers, immigrants) with the voices of those who profited, and ask whose records survived and why.
- Primary sources are reproduced word for word, including period language and dialect transcribed by interviewers. Before reading, discuss who recorded each source and for whom. Do not ask students to perform dialect aloud.
- Tell students before they see images of injured, captive, or dead people, and give them a way to step back.
- Distinguish what the sources show from what they cannot prove. Several stories in this exhibit correct popular myths; name the myth, then the evidence.
Guidance follows Learning for Justice, "Teaching Hard History: American Slavery" (Southern Poverty Law Center, 2018).

Part 2Read
The deadliest workplace disaster in New York City history changed the relationship between government and the workplace. One Saturday afternoon in March, 146 people died in about eighteen minutes.
On March 25, 1911, fire broke out on the eighth floor of the Asch Building near Washington Square, where the Triangle Waist Company occupied the top three floors. Fed by cotton scraps and tissue, it spread within minutes. A door to one of the ninth-floor stairways was locked—a practice, the owners' critics charged, meant to prevent theft and to control workers' comings and goings. The single exterior fire escape twisted and collapsed under the weight of those who reached it, and fire department ladders could not reach the upper floors. Within about eighteen minutes, 146 workers—most of them young Jewish and Italian immigrant women, the youngest fourteen years old-were dead. The tragedy galvanized a generation of reformers and produced the New York State Factory Investigating Commission, chaired by state senator Robert F. Wagner with Assemblyman Alfred E. Smith as vice-chair, whose work helped lay the political foundation for the New Deal.

These excerpts are quoted word for word, including the spelling and language of their time.
Document A
Eyewitness at the Triangle
William G. Shepherd, United Press, March 25, 1911 (published March 27, 1911)
The firemen raised the longest ladder. It reached only to the sixth floor. I saw the last girl jump at it and miss it. ... The floods of water from the firemen's hose that ran into the gutter were actually stained red with blood. I looked upon the heap of dead bodies and I remembered these girls were the shirtwaist makers. I remembered their great strike of last year in which these same girls had demanded more sanitary conditions and more safety precautions in the shops. These dead bodies were the answer.
Context: Shepherd, a reporter who happened to be in Washington Square, phoned in this account as the fire burned; it was telegraphed to newspapers nationwide. It was many Americans' first picture of the disaster that killed 146 garment workers.

Document B
Speech at the Triangle Fire Memorial Meeting
Rose Schneiderman, April 2, 1911
I would be a traitor to these poor burned bodies if I came here to talk good fellowship. We have tried you good people of the public and we have found you wanting. ... This is not the first time girls have been burned alive in the city. Every week I must learn of the untimely death of one of my sister workers. Every year thousands of us are maimed. The life of men and women is so cheap and property is so sacred. There are so many of us for one job it matters little if 146 of us are burned to death. ... I know from my experience it is up to the working people to save themselves. The only way they can save themselves is by a strong working-class movement.
Context: Schneiderman, a Women's Trade Union League organizer and former garment worker, spoke at the Metropolitan Opera House at a meeting called by civic leaders. Her speech, printed in The Survey, became one of the most quoted statements of the American labor movement.

Corroborate
Compare "Eyewitness at the Triangle" (William G. Shepherd, United Press, March 25, 1911 (published March 27, 1911)) with "Speech at the Triangle Fire Memorial Meeting" (Rose Schneiderman, April 2, 1911). Where do they agree, where do they differ, and what might explain the differences?
Part 6Discuss
- What details in Shepherd's account show that the fire department's equipment could not save the workers?
- Schneiderman spoke to a mostly wealthy audience at a memorial meeting a week after the fire. Why does she refuse to "talk good fellowship," and what does she demand instead?
- Shepherd connects the dead to the 1909 strike. How does the chapter narrative support or complicate his claim that "These dead bodies were the answer"?
- Schneiderman argued that workers must "save themselves" through a strong labor movement; New York responded mainly by passing safety laws. Which approach better protects workers today, in warehouses here or garment factories abroad? Argue your position.
