100 feet, the smoke being licked by darting tongues of flame.”

Outside, said a visiting coal magnate, glass covered the street like a snowstorm; wounded people and severed body parts lay scattered everywhere. The blast, which witnesses said tossed a nearby automobile 20 feet in the air, also stove in the offices of J. P. Morgan, just across from the bomb cart, decapitating the firm’s young chief clerk, William Joyce, who had been seated near the front. Morgan himself was vacationing in Britain. “This bomb was not directed at Mr. Morgan or any individual,” said the chief of the Secret Service, William J. Flynn. “In my opinion it was planted in the financial heart of America as a defiance of the American people. I’m convinced a nationwide dynamiting conspiracy exists to wreck the American government and society.” Whether or not the bomb had been aimed at Morgan, the estates of Morgan, Rockefeller, and other prominent men of the Street were now put under guard.

Two charred horse hooves, the only whole pieces of the horse or the wagon, landed at the foot of Trinity Church, into which a number of the wounded had struggled, seeking refuge from the fire and acrid smoke. Detectives carried the blackened horseshoes to 4000 blacksmiths along the Atlantic seaboard but came up only with the recollection of an Elizabeth Street smith, Dominik De Grazia, that he had recently changed a shoe for a “Sicilian"-accented driver. Ten tons of broken glass were carted off to police headquarters, where they were panned for clues and kept for two years. Then, as now, most Americans held a particular ethnic picture of a terrorist; at that time, it was based on the Italian and Russian radicals credited with bombings over the previous ten years in Los Angeles, Chicago, New York, Boston, and Washington. A tremendously ambitious terror scheme —in which 36 bombs were mailed to wellknown Americans in Gimbel Brothers boxes to be opened on May Day 1919—had nearly succeeded. Half the packages reached their intended targets, while the rest were discovered in a New York City post office.

As with other suspicious disasters, multiple scenarios for the explosion emerged almost immediately. Attorney General A. Mitchell Palmer thought the Wall Street attack must also be the work of anarchist or Bolshevik groups, and he quickly arrested the head of the Industrial Workers of the World, Big Bill Haywood, “as a precaution.” A less sinister, and less popular, explanation claimed the horse cart belonged to a dynamite company and had simply gone off upon hitting a cobblestone, but by day’s end the fire department had accounted for all such deliveries. “Authorities were agreed that the devastating blast signaled the long-threatened Red outrages,” the Times reported on its front page the day after, while an adjacent article followed the far weirder story of “Two Cards of Warning” sent by the former

ninth-ranked men’s tennis player, Edwin Fischer, who had vaguely predicted the explosion to his friends.

Fischer, a seldom-employed 44-year-old sportsman from the Upper West Side, had picked both September 15 and 16 as likely days for the attack; he had also warned a groundskeeper at his tennis club and a stranger on a train and had told a Toronto bellboy that some millionaires were soon to get what they had coming. His brother-in-law, who caught up with him in Ontario after he had mysteriously fled, reported that Fischer had twice been committed to sanitariums but had nevertheless shown psychic powers for several years. Dr. Walter F. Prince, at the American Institute for Scientific Research, told reporters it was possible Fischer had received a “psychic tip” of the bomb plot, like “picking up a wireless message.” Fischer, it turned out, predicted bad things happening to Wall Street pretty regularly. He was returned to New York and held at Bellevue Hospital, but after he told detectives that he was an alchemist and a sparring partner for Jack Dempsey and much more, they pronounced him harmlessly (if annoyingly) insane.

In his excellent history of Wall Street in the twenties, Once in Golconda, John Brooks suggests other explanations for the bombing: a botched robbery or an attack on the Treasury. On the day of the explosion, $900 million in gold bars was being moved out of the Sub-Treasury Building, which was next door to the new Assay Office, where the deadly wagon was parked. At the time of the explosion, workmen at the Treasury had just closed the side-entrance doors for lunch, possibly saving themselves as well as the gold.

But the answer to this mystery, unlike later inscrutable tragedies such as the TWA disaster, may have been disappointingly plain. Postal workers found circulars mailed a block away between 11:30 and 11:58 on the fatal day: “Remember/We will not tolerate/any longer/Free the political/prisoners or it will be/sure death for all of you/American Anarchist Fighters.”

The Anarchist Fighters had been linked to, among other things, the May Day bombing scheme of the year before and to radical groups (including what newspapers called the notorious “Galliani gang") around Lynn, Massachusetts, a place federal authorities then considered “the most dangerous spot in America,” according to a later investigator. Still another theory had it that the Wall Street bombing was revenge for the September 11 murder indictment of two Italian-born anarchists in Dedham, Massachusetts, Nicola Sacco and Bartolomeo Vanzetti.

Just as now, a recent immigrant group found itself broadly and unfairly blamed for the possible work of a few whose horrific violence had its roots in Old World politics. Americans of the 20s waited months and then years for the case to break, but no one was ever caught. Nine years after the attack, Sidney Sutherland wrote in Liberty magazine, “If the Wall Street bomb explosion was the result of a murder plot, it speaks eloquently for the bond of silence

which the lawless world imposes on its members.” Over the decades, the feeling returned that this kind of thing happened in other places; even after the horror in Oklahoma City, Americans’ day-to-day lives were hardly altered, except we now were routinely asked at airports whether we’d packed our own bags. However, with the fiery attack on the Pentagon, the destruction of the Twin Towers, and the taking of so many thousands of lives, that old feeling and style of life will likely never return.
