Medical Department during the Civil War. The example shown in the catalogue of the. BILLINGS MICROSCOPE COLLECTION of the UNITED STATES ARMY MEDICAL MUSEUM in figure no. "102" shows that their example is lacking one of its milled course focusing knobs.
This microscope by Zentmayer is the earliest example of a microscope that was designed specifically for wartime field hospital use. It was related to the contemporaneous rise of the germ theory of disease by brought forth by Dr. Louis Pasteur in the late 1850s. Though this stand is not a actual field microscope by the design, this is the first microscope ever to be designed specifically for front-line (and wartime) hospital efforts. Thus the UNITED STATES ARMY HOSPITAL is a milestone in the history of the military portable microscope.The Zentmayer "ARMY HOSPITAL" microscope on offer is fitted with two later Bausch & Lomb objectives and has it's original wheel of stops below the stage. The mirror cell assembly is original to the stand. The walnut wood box is original, as is it's brass carry handle, however, it does lack its accessory drawer and accessories. As stated prior, the BILLINGS MICROSCOPE COLLECTION of the UNITED STATES ARMY MEDICAL MUSEUM shows in their catalogue of the BILLINGS COLLECTION. The same microscope in figure 102. The catalogue also cites a second example. Of this exact same model in the collection - but it is not pictured.
The microscope on offer lacks its glass top stage and specimen holder of brass, but this is often the case with glass staged microscopes from this era, as they often got cracked or lost. The carry case has no key. At the time of the Civil War, there were only FOUR (4) active microscope makers in the United States and of these Joseph Zentmayer was able to secure a contract to produce the microscopes for use in the Civil War effort by the Northern forces.Most significantly is that this Zentmayer UNITED STATES ARMY HOSPITAL stand on offer has a number of "409, " which appears to be a somewhat early number in the scheme of things - and is certainly from the time of the Civil War and manufactured likely towards the end of the War in April 1865, as it is rumored that 1,000 (one thousand) of these Zentmayer Army Hospital stands were produced between 1862 and 1876 - with the major initial output going to the U. This model has a rectangular stage. This stage however was supplanted by a circular stage in 1876 and the instrument was renamed. Wear and minor surface abrasion throughout consistent with age and use but overall displays nicely.
Much of the original lacquer is no longer present. It looks like the scope was not polished though - and the surfaces still look nice and original. There are 1 - 2 teeth in the course focus rack that are worn and such causes the rack and pinion to slip at this point - but this will not happen if the objective is in place and above the stage; thus is not a very critical. The B & L objectives both work fine and over-all the scope's optics work fine as well. Please see all photos a s they are part of the description.
