The Iroquois Theatre Fire occurred on December 30, 1903, in Chicago, Illinois. It is the deadliest theater fire and the deadliest single-building fire in United States history. A total of 602 people died as a result of the fire.

Four Henning boys -- William, Charles, Edwin and James -- perished in the fire. Their mother, Emily Petit Henning, died several weeks later of smoke inhalation. They are all buried in Forest Hill Cemetery.
