The Iroquois Theater Fire occurred in Chicago on December 30, 1903. At least 602 people were killed; many were children. The theater, which had only been open one month, was considered to be architecturally excellent, and advertisements had declared it fireproof. The fire occurred during a sold-out performance of the musical Mr. Bluebeard. The fire began when one of the lights over the stage shorted out and ignited a muslin curtain. The fire quickly spread through the flies to the hanging scenery, and a fireball travelled from the stage to the back of the balconies. The high death toll was the result of a combination of faults in the design, construction, and operation of the theater. Lack of extinguishers and alarms, a malfunctioning asbestos curtain, sealed vents, a confusing layout, locked doors, and locked metal gates that blocked the balcony stairways all contributed to the fire's high death toll.
