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 Office and other police agencies. On April 29, Georgia Senator Thomas W. Hardwick, who had co-sponsored the anti-radical Immigration 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.
