The Knickerbocker Storm resulted in one of the deadliest disasters in Washington, D.C.'s history. This major snowstorm struck the region, delivering over 28 inches of snow on January 28, 1922. The blizzard caught many residents off guard, leading to significant disruptions. The sheer weight of the accumulated snow became too much for the Knickerbocker Theatre's roof to sustain. Packed with more than 800 moviegoers watching a feature film, the theatre was suddenly thrust into chaos when the roof collapsed, sending debris crashing down on the unsuspecting audience below.

Rescue operations unfolded under harrowing conditions as emergency services worked through the heavy snowfall to reach the trapped individuals. Firefighters and volunteers struggled but managed to rescue dozens from the wreckage. The rescue efforts revealed tragic realities as over 100 people were confirmed dead, and many more suffered injuries. The incident not only shocked the local community but also drew national attention, prompting inquiries regarding building codes and the enforcement of safety standards for public arenas.

In the aftermath, the disaster prompted city officials to reconsider regulations surrounding construction and structural integrity, leading to a stricter enforcement of codes. There were calls for a reassessment of how buildings could withstand extreme weather conditions. The Knickerbocker Theatre itself became a somber landmark, remembered as a reminder of the importance of safety in public spaces.
