"On This Day - January 28, 1922 - Knickerbocker Theatre Collapse.
In late January 1922, a winter storm dumped huge amounts of snow on Washington, D.C. Nonetheless, 400 people struggled through the lousy weather to attend a concert at the Knickerbocker Theatre on January 28th. As the conductor raised his baton, he felt a light dusting of plaster fall on his head and shoulders. Seconds later, the north wall cracked open and the roof collapsed. 95 people were killed and at least 100 injured. The accident was traced to inadequacies in design and construction combined with the added weight of the snow. The storm, which came to be known as the “Knickerbocker Storm,” is still on record as the worst weather event in Washington’s history.
