Through Italians and Sulfuric acid

April mail bomb attacks

In late April 1919, at least 36 booby trap dynamite-filled bombs were mailed to a cross-section of prominent politicians and appointees, including the Attorney General as well as justice officials, newspaper editors and businessmen, including John D. Rockefeller. Among all the bombs addressed to high-level officials, one bomb was addressed to the home of a Department of Justice Bureau of Investigation (BOI) field agent once tasked with investigating the Galleanists, Rayme Weston Finch, who in 1918 had arrested two prominent Galleanists while leading a police raid on the offices of their publication Cronaca Sovversiva.

The mail bombs were wrapped in brown paper with similar address and advertising labels. Inside, wrapped in bright green paper and stamped "Gimbel Brothers-Novelty Samples", was a cardboard box with a 6 by 3 by 1 inch (150 by 80 by 30 mm) block of hollowed wood, packed with a stick of dynamite. A small vial of sulfuric acid was fastened to the wood block, along with three fulminate-of-mercury blasting caps. Opening one end of the box (the end marked "open") released a coil spring that caused the acid to drip from its vial onto the blasting caps; the acid ate through the caps, igniting them and detonating the dynamite.

The Galleanists intended their bombs to be delivered on May Day. Since 1890 and the Second International, May 1 had been celebrated as the international day of communist, anarchist and socialist revolutionary solidarity. Seattle Mayor Ole Hanson, who had recently attained national prominence for opposing a general strike in Seattle, received one of the mailed package bombs, but it was opened by William Langer, a member of his office staff. Langer opened the wrong end of the box and the bottle of acid dropped onto a table without detonation. He took the bomb to the local police, who notified the Post Service and other police agencies. On April 29, Georgia Senator Thomas W. Hardwick, who had co-sponsored the Alien Anarchists Exclusion Act of 1918, received a similarly disguised bomb. It blew off the hands of his housekeeper when she attempted to open the package. The senator's wife was also injured in the blast, which severely burned her face and neck and a piece of shrapnel cut her lip and loosened several of her teeth.

News reports of the Hardwick bomb described its distinctive packaging and an alert post office employee in New York connected this to 16 similar packages which he had set aside a few days earlier for insufficient postage. Another 12 bombs were eventually recovered before reaching their intended targets. The addressees were the following:

  • Theodore G. Bilbo, Governor of Mississippi
  • Frederick Bullmers, Daily News editor from Jackson, Mississippi
  • Albert S. Burleson, Postmaster General
  • John L. Burnett, Representative from Alabama
