U.S. Navy Medical Department Microscope
by Zentmayer
From The Collection of Dr. Scott Watson. If you have sets you would like evaluated or would like to sell contact Dr. Scott Watson
Joseph Zentmayer was born in Germany in 1826. He emigrated to the US establishing his instrument business in 1853 in Philadelphia. He had a very successful career and was responsible for several developements in microscope design. His sons continued the business for several more years after his death in 1888. In the early 1860's he developed, manufactured, and sold the US Army Hospital model microscope to the goverment who shipped them to selected Union army hospitals and surgeons. The army model underwent many improvements and was sold for several years after the war. Below is an excerpt from the Army Surgeons Manual written by Dr Hammond on the care and maintence of the microscope for Union surgeons lucky enough to receive one. Also a price list from a 1876 advertisement. Extracted from the Illustrated Price List of Microscopes for Sale by T. H. McAllister Manufacturing Optician, No. 49 Nassau Street, New York 1876

ZENTMAYER'S U. S. ARMY HOSPITAL MICROSCOPE THE ZENTMAYER
Army Hospital Microscope was designed and constructed for the U. S. A. Medical Department in 1863, but it has since been very much improved. The Stand is sixteen inches high when arranged for use. Body, fine adjustment, and draw-tube are precisely the same as those of the "Intermediate". The bar is supported by one stout pillar. It has plane and concave mirrors, mounted similar to the former. The stage is made of a piece of plate glass, perforated in the centre, with brass mountings to receive the objects, and stage forceps; has also a stop for Maltwood's finder, and is kept down on the stage plate by a spring with an ivory pointed screw, similar to the revolving stage of the "Intermediate". The accessories are attached to a short tube below the stage, which may be removed when oblique illumination is required. Simplicity, steadiness, and convenience are the merits of this Microscope.
The binocular arrangement differs from the former only in tbe mode of adjusting the eye-piece for the distance of the eyes of different persons, which is accomplished by a connecting bar. The Zentmayer Army Hospital Microscope Binocular Body; with 4 Eye-pieces; 8/10 inch objective, 32° angular aperture; 1/5 inch, 85° angular aperture; Bull's-eye; Camera Lucida; Stage Micrometer, and Mahogany Case............................................... $185 00
Monocular Body; with 2 eye-pieces, and same accessories as above..................................... $136 00 The above is the manner in which the Stand is fitted out for the United States Goverment Hospitals; it may, however, be fitted out, if so desired, with any object-glasses or accessories from the lists.
The US Army Model in this collection was issued to the US Navy and is inscribed on the base "US Navy Med Dept". It is also marked on the base with serial number 686. No records still exist to identify date of manufacture with serial number but most likely produced in 1860's based on low serial number. This is a second generation model with improvements which include bilateral(two) large focus knobs instead of just one which was on the first generation. A similar model is on display at the Army Medical Museum at the Armed Forces Institute of Pathology in Washington, DC.
