The Rhoads Opera House, located in Boyertown, Pennsylvania, caught fire on January 13, 1908 during a church-sponsored stage play. The fire started when a kerosene lamp was knocked over, lighting gasoline from a stereoscopic machine. The stage and auditorium were located on the 2nd floor and all auxiliary exits were either unmarked or locked. One fire escape was available but unable to be accessed through a locked window above a 3 foot sill. 171 people perished when the exit was crowded against to escape the fire. Entire families were wiped out.
