Ambrotypes Reveal Forgotten History!

Mystery Pictures Discovered

A local historian friend, Peter Miller, provided copies of two probable ambrotype images, which appear to be from the 1850s. Peter was permitted to copy the originals from an old owner who claimed to be related to one of the pictured men, named Thompson. It is the machine, itself, that is the real subject and reason for these pictures to have been made!

An earlier version of this post identified these images as daguerreotypes. We have not seen the originals, but agree with the comments two readers have made, below. Ambrotypes were albumen coated glass, and would account for the crack lines in these images. We now presume these to be ambrotypes.

Non-Human Subjects, from these years are Rare

Remember that in the 1850s, only professionals made photographs, and the vast majority were portraits, made at the artist’s studio. Taking photographs of a machine in a factory would have been a special and costly job.

Jones & Thompson – Greenfield, Massachusetts

A company, named Jones and Thompson, operated most of our museum site in the 1850s. They ran a foundry and produced iron products. They also may have owned and operated the Green River Mills and dam. Lacking better information, we might easily imagine their metal industry as being like a large scale blacksmith shop. Maybe their products were just simple farm and trade tools. What did they really make? Did they supply a traditional market, or were they “high tech”? We knew little about Jones & Thompson, aside what we learned from the old maps. Is it possible that these two pictures might reveal a lost story?

Seeking an Answer

Our President, Jim Terapane, followed a hunch and began searching U.S. Patents awarded to residents of Greenfield. He came up with this!

The Pictures Match the Patent Drawings

The patent application for this clapboard planing machine mentions three names. Edwin Jones as claimant, and witnesses Hugh M. Thompson and Charles Mattoon. How much of a stretch is it, to presume that these are the same men standing in our picture?
We could also speculate that these two expensive pictures were actually made to document the machine for its patent application. If true, these two pictures are almost certainly from 1856 and that makes them the earliest photographs we have of Greenfield’s manufacturing history!

What Else May Still Be Discovered?

Please imagine the excitement we feel, when discovering such a lost bit of history! First, an unexpected piece of our imperfect jigsaw puzzle appears and challenges us to identify it. Then, imagine our thrill when we discover this piece reveals a new detail of the past!
Help us! Keep your eyes open for more historic gems, such as this. So much is already lost to time, but who’s to say what still might survive and contribute to our historic “jigsaw puzzle”?

  1. These are probably not daguerreotypes but ambrotypes. First of all dags were rarely made by 1856, ambrotypes were first made in 1852. Second the image on the left shows the type of crazing on the surface that only would happen with an ambrotype since it is made with an emulsion. Sometimes in the process or when they are stored in poor climates, the glass and emulsion expand and contract at different rates causing this. You can also see this a little on the image on the right as well.


  2. The photograph on the left is probably an ambrotype. Daguerreotypes don’t have emulsion cracks from emulsion shrinking. Ambrotypes were being made in 1856. It could also be a collodion copy of a daguerreotype. Can’t tell for the one on the right, but probably also an ambrotype.

  3. Well, I agree with the observations Michael and Richard made. I have not seen the originals, so needed to presume my friend’s story was accurate. I am still pretty certain about the date, because the machine matches the patent application. I am aware Ambrotypes are albumen on glass, while dags were silver plated copper, sensitized with iodine. Am I correct in presuming that Ambrotype emulsion would also allow for a faster exposure? These pictures appear to be indoors, with standing people pictured. These images would have been very difficult to make with the likely available light and long exposure. I will leave the page up, as is, for now, but will look into this shortly.

  4. Re, Utube abt Proximity Fuse:

    My aunt worked during WW2 in a secret room in downtown Worcester MA, making very small tubes with 4 or 5 other women. So far its never been confirmed what company it was. Best guess was Raytheon. Likely only her SS records will confirm! She described to me ( before she passed on) what she was actually was doing in the assembly room. Is it possible the section in the Utube video here is in that room of women?

    • Anything is possible. We believe it was indeed Raytheon (at Lunt Silversmith’s in Greenfield) that was also making vacuum tube components. Visit us next month, and I will show you a tube and a couple complete fuses.

    • I initially thought so, as well. There are signs of emulsion cracks and other imperfections to suggest they are from albumen wet plates.

  5. Anson & Edwin Clark in Western MA in period of 1840-1850 had inventions & working models for wood planer machine for making piano rare wood veneer.
