On September 16, 1920, a bomb exploded in front of the offices of J.P. Morgan & Co. at the corner of Wall and Broad streets in downtown New York City. No group claimed responsibility for the crime, which remains unsolved. However, various theories were put forth. One possibility was an attempt to rob the adjacent Sub-Treasury Building, where $900 million in gold bars was being moved that day. A more widely accepted theory is that the bombing had been an act of terrorism performed by “Reds”—anarchists and communist sympathizers—who wanted to shatter the symbols of American capitalism.
