The First Photograph of a Smell

It leaves me with such a cozy feeling to not find what I think is an obvious-but-odd phrase in Google.

 And that's what happened with "the first photograph of a smell" (or "photograph of a smell" or odor, for that matter),  as shocking to the senses as it might be.

There are long and interesting lists of firsts in photography: the first color photograph (Maxwell, 1867, but impermanent), the first photograph of a human face, the first photograph of the moon, the first photo of a planet, and so on, tirelessly, until we see how many derivations of "firsts" there are. (We can go from first photo of human to first photo of a human face to first photo of a human in motion to the first photo showing human hands to the old human recorded by photography tot eh first photo of a couple to the first photo of a human with a tool and on and on.) There is a shorter list of "first photographic non-photograph of a photograph" (?!) that I wrote about in an earlier (illustrated) post, but we won't go there today.

Here is a "first" though that I think hasn't been dealt with too terribly much: the first photograph of an odor.

These beautiful images appeared in the 10 September 1938 issue of The Illustrated London News and were exhibited at the 83rd Annual International Exhibition of the Royal Photographic Society, and were made by H. Devaux (who evidently, according to the snippet of an obituary that I can see from Science magazine, was a plant physiologist and "pioneer of surface physics"
who died in 1956). The note accompanying the photographs read: "The emission of an odor involves volatillisation of material. If an odiferous material is enclosed in a cell a few millimeters above a clean mercury surface, it is possible to collect on the surface of the mercury a monomolecular layer of the volatillising or odoriferous substance. If the mercury surface initially is covered with talc powder, the gradual formation of the monomolecules layer may be observed as the talc is gradually pushed away from the point immediately below the specimen of material."

The photos are that of the odors of a lily and of camphor. I don't know which is which, and a good story could be made up for either photo belonging to either item. Needless to say, these images are as gorgeous as they are unexpected, especially considering that they were made in 1938.

FOOTNOTE:

I'd just like to add here the first photograph of a human being--well, actually, it is the first photograph that just happens to capture a human in the emulsion (discussed very nicely on the Doug's Darkworld  blogsite.  Since the  exposure time was so terribly long for this image to be made, the moving people and horses and carriages on the street, all of the city-life bits, were necessarily spectral, invisible, to the photograph.  Only the stationary items were captured, and the only people captured here were two figures in the foreground, doing something or other that made them still for at least five minutes--long enough for their anonymous but famous photonic impressions to be captured.   Mr. Doug and others seem to think this is a man getting his boots shined--I agree.
