HIGGINS'
AUTOMATIC DUPLEX FINDER
John J.
Higgins, New York City 1888 - 1893
The Automatic
Duplex Finder was an early camera viewfinder,
patented by John J. Higgins of New York City on July 12, 1887, Patent No.
366,584.
Appearing in The Philadelphia Photographer, January 7, 1888, the finder measures
4" x 3" x 2". It
functioned simply by rotating the viewer upside down. In one position, the internal mirror falls
into a 45 degree position, permitting a waist-level view from the top. Rotating it once more causes the mirror to
fall flat, permitting an eye-level view from the rear.
It's size is considerably larger than finders
found on self-casing cameras of the 1890's although it could be used with any
camera, simply by resting it on the camera's body. Its introduction, prior to the emergence of
most self-casing cameras, suggests it was more intended for field camera use. This particular example has no mounting
hardware, or evidence that it was ever mounted on a camera. However, the patent's wording states that the
finder could be mounted, or be removable in use. An Internet search revealed a 2011 eBay
auction, where an Eastman dry plate camera was equipped with a Higgins
Automatic Duplex Finder.
The granting of Higgins' patent is mentioned
in the August 6, 1887 issue of the Scientific
American. Mention was also made
in a November, 1887 article in The
Photographer's World, stating that a "Dr. J.J. Higgins" has
"produced a model of his own invention". It was sold by George Murphy as "The
Higgins Patent Duplex Finder" in the 1890 issue of Photographic Mosaics, and it also
appears in G. Gennert's Descriptive Catalogue of Photographic Apparatus and Supplies
circa 1893, as the "Automatic
Duplex Finder". Higgins also held at least five other photographic
patents, one for a detective camera under Patent No. 371,458 dated October 11,
1887. It was designed to have
interchangeable body sections that permitted lenses to be easily changed, or to
store plate holders separate from the camera.
With only a few having been seen, one can
assume that production of the Automatic
Duplex Finder was very limited over an estimated 6-year period. You're not likely to come across one soon,
but I have no doubt that others exist.
