Knickerbocker Storm, Washington D.C.'s biggest snowfall, causes the city's greatest loss of life when the roof of the Knickerbocker Theatre collapses.
The Knickerbocker storm was a blizzard on January 27–28, 1922 in the upper South and the middle Atlantic United States. The storm took its name from the resulting collapse of the Knickerbocker Theatre in Washington, D.C., shortly after 9 p.m. on January 28, which perished 98 people and injured 133.
