New York City's most haunted house, the "House of Death" at 14 West 10th Street is supposedly haunted by 22 ghosts, the most famous of which is Mark Twain, who resided there from 1900-1901.
A Greek Revival brownstone, “Number 14″ was home to many members of New York’s elite, including Mrs. James Boorman Johnston whose husband had been a founding member of the Underground Railroad.
In 1900, the building became the residence of author Samuel Clemens (aka Mark Twain). Sightings of Twain decked in a white suit have been reported on the first floor and near the staircase. In the 1930s, a mother and daughter claimed to have encountered the author sitting near a window where he stated, “My name is Clemens and I has a problem here I gotta settle.” He disappeared moments later.
The house has been visited by multiple paranormal investigators who claim to have sensed the presence of a lady in white, a young child, and a gray cat. Tragically, the brownstone was home to a real life demon named Joel Steinberg. Steinberg was charged with first-degree manslaughter for beating his 6-year old daughter to death in 1987.
