The discovery
In 2020, a box of discs and plates relating to an early motion picture system was discovered in the USA. The owner Eli Nesmith, who inherited the material from his aunt and uncle, has been generous enough to allow details, images, and animations to be released on The Optilogue. The first part of this short blog series illustrated ten discs from the series, Part 2 showed another nine discs. In this post we further examine the nature of the find, and speculate on the possible origins and details of the missing associated machine(s).

The box
‘It is a curious contraption, with hinges along most sides and a 1.25-inch hole in one side that seems to have once served some purpose.’[1] Perhaps the hole was to allow for the insertion of a crank handle, if the machine was intended to be used while it was inside the box (assuming the hinged panels would allow for the lens side to be open, with suitable illumination).
The newspaper
The discs ‘were originally wrapped in newspaper from 1898 … the Brooklyn Daily Eagle’.[2]
The glass discs and plates
8-inch glass discs
These are eight inches in diameter with a central hole and a smaller off-centre hole presumably to receive a location pin. They carry either 24 or 40 negative photographs set slightly in from their outer edge, still and animated images from which are shown in Parts 1 and 2 of this series of posts.


3.25-inch glass plates
At least one of these shows a variant of the subjects recorded on the larger discs. This features two Black men performing a shoe shuffle while one plays the harmonica – the images are not exactly the same as the similar subject shown on the 8-inch disc. In this small plate shown here, one of the performers is on his knee, and they have swapped roles, with the other dancer playing the harmonica. It has not yet been determined whether any other 3.25-inch plates have variants of the subjects recorded on the larger discs.
The purpose of the plates is not known. It should be noted that 3.25 inches is one of the standard sizes for lantern slides of the period, especially in Britain, though some use of that size was made elsewhere.



Celluloid sheet
There is a single item made of celluloid, 8 inches square, with a positive version of an image sequence showing two boys fighting while a small crowd looks on.


The unknown camera / viewer / projector(s)
We know nothing about the camera(s) on which these discs were taken, or the machine(s) with which they were intended to be viewed or projected. It might have been a hybrid camera/viewer-projector. First, let’s take a look at some systems proposed by The Optilogue’s readers in the Comments on the first parts of this post series, and then some other possibilities. I have limited this review to the examples closest to the technical features and likely date range of the ‘Nesmith’ discs, and only those systems intended to be used as a camera as well as either a viewer or projector – viewing/projection-only devices have been excluded.
Cinéphote
Perhaps the closest that we have to a machine for taking and projecting/direct viewing this type of disc is the French Cinéphote of Huet, promoted in 1909. The Cinéphote was advertised as being designed for portrait work, rather than any other type of motion picture.



The central hole looks relatively smaller than those on the ‘Nesmith’ discs, and there is no second ‘pin location’ hole to ensure that the disc doesn’t slip. However, there is a photo of the camera/projector machine with a disc inside, and we can see that towards the outer edge of the ‘label’ there is a ring of holes for registration, one for each frame. These holes are not very evident in the published illustrations of the discs (you can buy a nice high-definition scan of this photograph from Getty Images for just £375). There’s another version of the image, plus more information and pictures, at the wonderful Media History Project.

In the Cinéphote viewer-projector (above left) the photo-frame would have contained a conventional photographic print, indicating the subject of the disc to be viewed through the lens, when this version of the device was used as a peepshow viewer rather than a projector. The Cinéphote disc (above right) is shown with 24 pictures arranged circumferentially. The 24 pictures are rectangular, portrait format, with black ‘V’ shaped areas to maintain their rectangular shape. With the ‘Nesmith’ discs, the pictures are wedge-shaped, so no black ‘V’ areas are needed. I have seen a reference to the size of the Cinéphote discs as 150mm, so smaller than the 8 inches (203mm) of the ‘Nesmith’ discs.
The pictures are a small distance from the edge of the disc, as with the ‘Nesmith’ discs. The decorated central area on the Cinéphote discs would not be necessary if users created their own blank discs. There were several models of the Cinéphote camera: one used 24 images in a ring (as do many of the ‘Nesmith’ 8-inch discs), while another used 75 pictures arranged in a spiral. The viewer-projector was a separate machine. I have not established the size of the Cinéphote discs, but I believe they were made on a celluloid base.
Despite the similarities, I don’t think the ‘Nesmith’ discs were taken with a converted (enlarged) Cinéphote machine, as there are too many differences. Also, I think the c.1909 date for the Cinéphote’s introduction, and the post-1903 dates for its patents, is too late. The ‘Nesmith’ discs are more likely to date from the 1890s.
Kinokam
This device was promoted in an article in the Optical Lantern and Cinematograph Journal in February 1906. It was 6 inches square, with the discs being approx 4.72 inches (12cm), much smaller than the ‘Nesmith’ discs, and the images were in portrait format. However, as with the ‘Nesmith’ discs, there were 24 pictures. The Kinokam negative discs appear to have been made of celluloid, and it seems that the prints made from them were paper, though celluloid positives might also have been made. The camera could be configured as a viewer, but probably not as a projector. There is an example (from the Will Day Collection) in the Cinémathèque française.[3]


The Kinokam seems to have disappeared very quickly, without details of its price being given. I once had the opportunity of briefly examining one of these but I don’t remember how the images were illuminated for viewing – perhaps there was an aperture in the back of the device. In 1989 the British Journal of Photography reported a forthcoming sale item: ‘Kinokam combined camera and viewer still in the maker’s box – an example of which has never before been sold at auction.’[4]
Neither the Kinokam nor the Cinéphote seem to have been made in any quantity and both are now extremely rare. The Kinokam was very probably never actually marketed.
24 Pictures
Both the Cinéphote (one version) and Kinokam used discs with 24 pictures arranged in an annular configuration, as did the machine that took the ‘Nesmith’ discs. However, some of the latter have 40 pictures, so an intermittent wheel or some other part(s) of the mechanism must have been capable of being changed, unless there was more than one camera/viewer.
An adapted design?
One possible origin of the missing ‘Nesmith’ machine was the ‘detective cameras’ for taking individual snapshots on discs, some of which had suitable mechanisms for adapting to sequence pictures. One of the first of these was the Thompson revolver camera.

Thompson / Gray / Thompson-Gray / Stirn cameras
Thompson’s detective revolver camera was made by the Parisian instrument maker A. Briois, and introduced in 1862. Four negatives were exposed on a 3-inch circular glass plate. Fewer than ten examples of this camera remain. Other disc cameras of the period included one made by Sands and Hunter, the Magazine Detective Camera, which was rifle-shaped and took 18 pictures on a disc. See the Science and Media Museum blog for more details of ‘camera guns’.

Robert Dempsey Gray, an experimenter in Boston, designed and arranged for manufacture a disc camera that eliminated the pistol/revolver/rifle aspect – not all subjects would have appreciated having a gun pointed at them – and became a slim disc-shaped camera that could be hidden beneath a jacket or waistcoat while photos were being taken through a buttonhole, so making the snapshotter much less conspicuous, more like a real ‘detective’.[6]
A later development of this camera was devised by Dr William Gilman Thompson – not the same person who invented the 1862 revolver camera previously mentioned – in cooperation with Robert Dempsey Gray, and known as the Thompson-Gray Camera. This was fitted with an f2 Petzval design lens, which permitted instantaneous exposures in good light. Changing the six-notch disc for one of 24 (or 40) notches, and some gear changes, might have been the method by which the ‘Nesmith’ device operated. A description appeared in the Scientific American Supplement in October 1886:
‘Thus every complete revolution of the central wheel in the floor of the box carries with it the dry plate, stops it, and moves it on again six times. The velocity of revolution of the plate is only limited by the rapidity with which one can turn the crank.’[7]
Dr Thompson wrote: ‘The apparatus was devised by Mr R.D. Gray (the inventor of the ingenious “vest camera” and other photographic improvements) and by myself. I described what was required and suggested various modifications and improvements, but the mechanical details were worked out exclusively by him.’ The Thompson-Gray development was a chronophotographic camera, with six exposures being taken in one second. One sequence that survives as drawings shows the phases of a frog’s beating heart. Gray went on to develop, in 1895, a 35mm film camera for motion pictures.[8]

The original R.D. Gray design was apparently purchased by C.P. Stirn, a German manufacturer, and sold by them in Berlin. C.P. Stirn’s ‘concealed vest camera’ was marketed in America by Stirn and Lyon, sole agents for the USA and Canada. It was introduced in 1886, and available until around 1892. There were two models, one 6 inches in diameter, the other 7 inches, the glass discs being somewhat smaller in each case. There were six pictures on each disc, but these were individual pictures, not intended for motion studies. The larger model took pictures 2.5 inches in diameter, which were suitable for making into individual-image positive plates by contact printing, for use in magic lantern projection. Advertisements claim that 18,000 cameras were sold in four years.
Some possibilities
In an interview in 1891, Thomas Edison mentioned Mr Hemment, ‘the man who photographs running horses in a thousandth part of a second’, but was limited to ‘half a dozen photographs at a time’. The maximum of six photographs suggests that John C. Hemment, a British immigrant based in New York, could perhaps have been using a Gray, or Thompson-Gray, camera, an indication that one of these disc cameras might have been used by someone other than Dr Thompson in an attempt to capture movement. This is speculation, but an interesting possibility.[9]
It is possible that the ‘Nesmith’ machine was based on an adapted, Stirn-manufactured Gray camera, or a Thompson-Gray chronophotographic camera, or perhaps designed around the associated patents, or the Demenÿ patents.[10] The Thompson-Gray mechanism design would have operated well at the 2 fps or so that was indicated by the limited action capture of the ‘Nesmith’ device. Of course this is conjecture, and the machine or machines might have been totally different and designed from scratch by someone completely unknown to historians. As with the commercial designs that are known to us, the ‘Nesmith’ camera must have had a mechanism that allowed just the required number of exposures before blocking the disc movement or the lens, otherwise the first ring of images taken would have been obscured by subsequent exposures.
We are appealing to historians and researchers to send their suggestions and thoughts concerning the disc subjects (first, see the Comments section for Parts 1 and 2). Those received in time will be incorporated into the final post in this blog series.

A small clue, maybe?? Looking at an octagonal plate from the Marey photographic gun, or rifle, which held 12 images of about 1 centimeter width (the plate in front of me records the flight of a bird), it is easily seen that while the tops and bottoms of each image are parallel, the sides of each image are somewhat slanted, giving each image overall a trapezoidal shape. While the images are widely spaced on the Marey apparatus, this side shape is necessary on any
camera using a circular plate because without the slanted slides the bottoms of each image would overlap each other, as they are closer to the centre of the disk. The images in the Nesmith disks have significantly stronger slants to their sides, much more pie-shaped, but the principles hold: I would look for apparatus that used a circular disk to take the images in the first place — there is no reason for the image shape of the Nesmith disks with any other form of sequence camera. Two further points: the Marey photographic gun was very widely publicised and illustrated at the time, and could easily have been the basis of a new construction by an experienced photographic technician; and this type of apparatus needed only a single lens, much less expensive than the multiple-lens setups of Muybridge or Anschutz, so something that again could be pursued by someone without substantial financial resources. So, in this case, an apparatus that did not need to be ‘manufactured’ and come publicly to market to justify its construction. The mystery may be solved in correspondence, or memoirs, or minutes of a photo club rather than by advertisements or catalogues. Makes it a mystery all the more satisfactory when solved……..
