History & local legend
Jonathan Williams and three fellow paranormal investigators opened Gettysburg’s International Museum of Spiritual Investigations in March 2010. Their three-room museum occupied a Civil War-era house on Baltimore Street and displayed material about spirit photography and other reported phenomena.
Among its exhibits was William Mumler’s famous photograph of Mary Lincoln with a pale image of Abraham Lincoln behind her. A separate nighttime photograph, contributed by a reenactor, was taken on Seminary Ridge; Williams said it contained fourteen soldiers. Those images were exhibits from elsewhere, rather than photographs of activity in the museum itself.
Williams also told visiting reporter Larry Alexander about experiences inside the Baltimore Street building. He and colleagues reported footsteps, fleeting figures, voices calling staff by name and the sensation of being tugged.
