Wreckage of Chicago's Federal Building
Sep, 1918
Just after 3:00 p.m. on September 4, 1918 a very powerful bomb exploded in the Adams Street entrance of Chicago's Federal Building which contained a post office and a federal court. Four people were killed and dozens more were injured. It was widely believed that the bomb was planted by the Industrial Workers of the World (I.W.W.) in revenge for the conviction and sentencing of I.W.W. leader, "Big Bill" Haywood, and 94 other members for seditious activities. The courtroom where Judge Kenesaw Mountain Landis presided over the trial of Haywood and the other I.W.W. defendants was on the sixth floor of this building. Judge Landis had sentenced Haywood to 20 years in prison. Haywood was in this building on the 8th floor in the "cage room" of the United States Marshal's office when the bomb exploded.
