Mug shot [SEP] History
The earliest photos of prisoners taken for use by law enforcement may have been taken in Belgium in 1843 and 1844. In the United Kingdom, police in London were photographing criminals by 1846. In Liverpool and Birmingham they were doing so by 1848. By 1857, the New York City Police Department had a gallery where daguerreotypes of criminals were displayed. The Pinkerton National Detective Agency began using these on wanted posters in the United States. By the 1870s the agency had amassed the largest collection of mug shots in the US. The paired arrangement may have been inspired by the 1865 prison portraits taken by Alexander Gardner of accused conspirators in the Lincoln assassination trial, though Gardner's photographs were full-body portraits with only the heads turned for the profile shots.
