“Over 5,000 people attended the mass memorial meeting called by the Anti-Militarist League for Berg, Hanson, and Caron, the three anarchists killed in the Lexington Avenue explosion. Over 800 policemen monitored the meeting, while Berkman, Abbott, Edelsohn, Elizabeth Gurley Flynn, Carlo Tresca, David Sullivan and Charles Plunkett all spoke for their dead comrades.
“‘The Lexington Avenue bombing was the July 4, 1914 explosion of a bomb in an apartment at 1626 Lexington Avenue in New York City, killing four people and injuring dozens.
“In July 1914, two members of the Lettish section of the Anarchist Black Cross, Charles Berg and Carl Hanson began collecting dynamite they had obtained from Russia. Plotting with them was Industrial Workers of the World (IWW) member Arthur Caron. They stored the dynamite at the apartment of another Anarchist Black Cross member, Louise Berger. Berger was an editor of Emma Goldman’s Mother Earth News. Several meetings were held at the Ferrer Center, where they devised a plan in which Caron, Berg, and Hanson were to plant a bomb at John D. Rockefeller’s home in Tarrytown, New York.
At 9 a.m. on July 4, the bomb intended for Rockefeller exploded prematurely at Berger’s apartment, killing Hanson, Berg and Caron.’
