The Wall Street bombing was an act of terrorism on Wall Street at 12:01 pm on Thursday, September 16, 1920. The blast killed 30 people immediately, and another eight later died of wounds that they sustained in the blast. There were 143 seriously injured, and the total number of injured was in the hundreds.
The 38 fatalities were mostly young people who worked as messengers, stenographers, clerks, and brokers. Many of the wounded suffered severe injuries. Police officers rushed to the scene, performed first aid, and appropriated all nearby automobiles as emergency transport vehicles. Often throughout the Gilded Age, radical ideology and violence was used as a form of protest by groups to initiate change. When simple protests were not enough, these extremists would resort to ruthless measures to be heard. Although the violence proved to be detrimental to their overall cause, many historians saw that this was a clear point of radical behavior aimed at facilitating transformation throughout the classes. They observed that the Wall Street bomb was packed with heavy sash weights designed to act as shrapnel, then detonated on the street in order to increase casualties among financial workers and institutions during the busy lunch hour.
Officials eventually blamed anarchists and communists for the Wall Street bombing. The Washington Post called the attack an "act of war". Most of the initial investigation focused on anarchists and communists, such as the Galleanist group, whom authorities believed were involved in the 1919 bombings. Buda (at that time known by the alias of Mike Boda) had eluded authorities at the time of the Sacco and Vanzetti arrests, was experienced in the use of dynamite and other explosives, was known to use sash weights as shrapnel in his time bombs, and is believed to have constructed several of the largest package bombs for the Galleanists.
After leaving New York, Buda resumed the use of his real name in order to secure a passport from the Italian vice-consul, then promptly sailed for Naples.
The bombing is the subject of the PBS series American Experience episode "The Bombing of Wall Street", broadcast in February 2018.
Additionally, the bombing is depicted in the 2012 period thriller film No God, No Master.
