Canonsburg Opera House Disaster

The Morgan Building in Canonsburg, Pennsylvania

Date: August 26, 1911

What happened
During a movie showing at the Canonsburg Opera House, a projector malfunction caused a brief flash of light. Although there was no fire, someone shouted “fire,” and a panic broke out. Patrons rushed to the exit on the second floor, but the doorway was too narrow and the crowd became trapped.

Building details
The Morgan Building sits at the corner of North Central Avenue and Pike Street. The theater was on the third floor. After a 1902 renovation, the auditorium could seat 884 people (552 on the floor, 132 in the balcony, 200 in the gallery). The building had a single 26-step staircase leading to the main entrance/exit, with doors that could swing inward.

Why it was deadly
The main doors opened inward and were latched during the rush, creating a bottleneck as people moved from the narrow staircase to the doorway.

Casualties
26 people died: 24 inside the stairwell, 1 rescuer was killed by a falling object, and 1 audience member who escaped across the street died from panic-related causes after being crushed.

Aftermath
Less than three weeks after the disaster, the auditorium was converted into apartments and the seats were removed.

Related events
About 16 months later, a false shout of “fire” caused a panic at the Italian Hall in Calumet, Michigan. These events received wide attention at the time and are sometimes discussed in relation to later debates about unprotected speech and public safety.
