In 1914, an otherwise non-descript tenement in East Harlem looked like this:
The location is on Lexington Ave. near 103rd Street East, and remarkably, they repaired this damage – rather than tear down the building (admittedly, the building was only 4 years old at the time – it was built in 1910):
At 9:16 a.m. on July 4, 1914, a premature dynamite explosion in an anarchist bomb factory blew the roof off a tenement at 1626 Lexington Avenue, near 103rd Street, wrecking three floors, killing four people, injuring a score of others and spewing debris for blocks.
The police identified the intended target of the homemade bomb as John D. Rockefeller. Protests were staged at their homes, offices in Manhattan and at their estate in Pocantico Hills in Westchester County, where two of the alleged bomb-makers had once wound up on trial.
The police linked the deceased bombers to the Industrial Workers of the World, specifically to Alexander Berkman and Emma Goldman, radicals who a few years later would be deported to Russia.
The 1914 explosion killed Charles Berg, Arthur Caron and Carl Hanson, all linked to the Rockefeller assassination plot, and Marie Chavez, who rented a room in the sixth floor apartment but was not believed to have been involved in the conspiracy.
A year later, the police found another bomb hidden in the driveway of the Tarrytown home of John D. Archbold, the president of Rockefeller’s Standard Oil.
