Possible revenge for the arrests of Sacco and Vanzetti and/or the deportation of Luigi Galleani

The bombing was never solved, although investigators and historians believe it was carried out by Galleanists, a group responsible for a series of bombings the previous year.

Attack[edit]

At noon, a horse-drawn wagon passed by lunchtime crowds on Wall Street and stopped across the street from the headquarters of the J.P. Morgan & Co. bank at 23 Wall Street, on the Financial District's busiest corner. Inside the wagon, 100 pounds (45 kg) of dynamite with 500 pounds (230 kg) of heavy, cast-iron sash weights exploded in a timer-set detonation,[4]: 77  sending the weights tearing through the air.[5] The horse and wagon were blasted into small fragments, but the driver was seen by witnesses leaving the vehicle and escaping down a side street.[6][7]


The 40 fatalities were mostly young people who worked as messengers, stenographers, clerks, and brokers. Many of the wounded suffered severe injuries.[2]: 329–30  The bomb caused more than US$2 million ($30.4 million today) in property damage and destroyed most of the interior spaces of the Morgan building.[8]


Within one minute of the explosion, William H. Remick, president of the New York Stock Exchange (NYSE), suspended trading in order to prevent a panic.[9] Outside, rescuers worked feverishly to transport the wounded to the hospital. James Saul, a 17-year-old messenger, commandeered a parked car and transported 30 injured people to an area hospital.[10] Police officers rushed to the scene, performed first aid, and appropriated all nearby automobiles as emergency transport vehicles.[11]

In media[edit]

The bombing has inspired several books, notably The Day Wall Street Exploded by Beverly Gage, The Death Instinct by Jed Rubenfeld.[27]


Upton Sinclair writes about this event in the book Oil! He argues that there was no conspiracy, rather the bombing was negligence from a truck driver carrying hazardous material who ignored the rules for their safe transport.[28]


The bombing is the subject of the PBS series American Experience episode "The Bombing of Wall Street", broadcast in February 2018.[29]


Additionally, the bombing is depicted in the 2012 period thriller film No God, No Master.
