A photograph (well, actually a Photogenic Drawing - basically an early photogram) just know as "Leaf" is coming up for auction at Sotheby's and may possibly be the oldest photographic representation in exisitence.
It had previously been attributed to William Henry Fox Talbot, one of the founding fathers of photography. Fox Talbot made a number of other leaf prints and this one was though to have been made by him in about 1839.
But new research suggest it might well have been made as early as 1790 by Thomas Wedgwood, James Watt or Humphry Davy, who were all early experimenters in photography.
"...Sotheby's says research by a leading photo expert suggests otherwise - that several early photo experimenters could be the authors, including Thomas Wedgwood, James Watt and Humphry Davy, who worked in the medium decades earlier. If that theory is true, it means the photo could have been made as early as 1790..
All six photogenic drawings were contained in an album belonging to Henry Bright of England whose family had a close social connection to the Wedgwoods, Watt and Davy, adding further support to the theory that "Leaf" could be by one of them, Sotheby's said...
The work of Wedgwood, of Wedgwood china fame, Watt and Davy was documented in their day and cited in standard histories of photography, but no examples have ever been identified, Sotheby's said... (more at the CBC)
You can check out the auction at Sotheby's - item #43 (you need to log in to see the full details) - and get your wallet out on April 7th. Maybe you could own a bit of photographic history.... (oh and take a look at some of the other work in the auction while you are there).
There is a fairly extensive essay in the online catalogue:
It still sounds a bit of a long shot, but not impossible by any means. It would certainly be nice for the Brits to have been the ones to have fixed this particular shadow first :-)
"In 1984, Sotheby's in London sold a small group of anonymous photogenic drawings that were originally part of an album assembled by one Henry Bright. The photogenic drawing offered here was among that group, and after the Sotheby's sale, it was re-attributed to William Henry Fox Talbot. Dr. Larry Schaaf, the Talbot authority, has questioned that attribution, and in the essay below, explores other possibilities of authorship, including Thomas Wedgwood or members of his circle.
It may seem surprising that photogenic drawings are such very rare survivors. William Henry Fox Talbot published the full details of how to make them by February 1839. While fraught with uncertainties, the process was relatively simple, used readily available materials and was widely published in the popular journals in the months following Talbot's disclosure. Public demonstrations were given and kits of materials advertised in the newspapers. One must assume that many hundreds of amateurs, scientists, artists, and others were fascinated by getting nature to draw her own image. Following Talbot's published instructions, an experimenter had only to take a sheet of writing paper, soak it in a weak solution of common table salt, and then brush it with silver nitrate. Light sensitive silver chloride would be formed within the fibers of paper. This sensitive paper was then placed in the sun under a leaf or other object and within minutes the energy of the light would reduce the silver chloride to tiny particles of silver, appearing red or purple. The image was a negative, of course, for where the object blocked the light, nothing happened, but where the light reached around or through the object, the paper darkened. At this stage, it could be examined by candlelight, or fixed to make it more resistant to the sun's rays.
Yet virtually none of what we know must have been produced seems to have survived.(1) One explanation for this loss might lie in human nature, for the succeeding generations that have proven to be dismissive of great-aunt Susan's amateur watercolors would probably have thought even less of her sun drawings. Perhaps more importantly, most of these would have remained sensitive to light and those most treasured and admired, paradoxically, probably got the most viewing and were consequently destroyed. The largest known body of surviving photogenic drawings was done by Henry Talbot himself. Yet this leaf, and its companions, do not fit into the corpus of known work by Talbot and his circle. That leads us to contemplate just how it came to be created - and why it has survived."...(Sotheby's)
