The Story Behind a Photograph | Wall Street After the 1920 Explosion... A Glimpse of a Mystery Unsolved for More Than a Century
On the morning of September 16, 1920, New York’s financial district was moving toward the lunchtime peak when Wall Street turned in moments into a scene of destruction and chaos. The archival photograph held by the Library of Congress documents the aftermath of the explosion in the heart of the financial district. It is neither a reenactment nor a generated image, but a visual record of an event that later became one of the most famous unsolved cases in American history.
What Happened on Wall Street?
According to the Federal Bureau of Investigation, a man arrived in a horse-drawn cart in the area opposite the J.P. Morgan building and the U.S. Assay Office, then left. Minutes later, the cart exploded amid the lunchtime crowds. More than 30 people were killed immediately or died from their injuries, and about 300 others were wounded.
FBI records show that investigators did not initially know for certain whether the explosion was deliberate. The overnight cleanup of the site also led to the loss of physical evidence that could have been highly significant by modern investigative standards. The following morning, Wall Street returned to work despite the shattered windows and traces of the blast.
The Photograph: A Street Bearing the Marks of the Moment
The photograph selected for this feature is held by the Library of Congress under the title “Wall St. explosion,” and the library dates it to September 1920. It shows the aftermath of the bombing in New York’s financial district and comes from the Bain News Service collection. Its digital ID is LC-DIG-ggbain-31205, and the library states that there are no known restrictions on publication in the item’s rights information.
The value of the image lies in the fact that it does not present the event as a number in a history book, but places the viewer before a real street whose appearance changed within minutes. The buildings, crowds and traces of destruction transform the case from a distant account into a moment that can be visually read more than a century later.
A Wide-Ranging Investigation… and an Ending Without a Suspect
New York police and fire departments, the federal investigative agency that preceded the FBI, and the U.S. Secret Service took part in the investigation. Investigators interviewed hundreds of people and tried to reconstruct the bomb and the mechanism of the explosion. Leaflets bearing messages linked to anarchist movements were also found, but the investigation did not produce evidence sufficient to convict those responsible for the attack.
The FBI says suspicion turned toward followers of the Italian anarchist Luigi Galleani, but the case was never proven, and the identities of those who carried out the bombing remained unresolved. In this way, the photograph became part of the memory of a historic case whose conclusion remains open.
Why Does This Photograph Still Matter?
More than a century later, the photograph’s importance lies not only in documenting the destruction. It is a reminder of how criminal-investigation methods have changed, how fragile evidence can be in the first hours after disasters, and how a documented archival image can preserve details that numbers alone cannot convey.
