French Drum Microscope with stage fine focus, c. 1850
(Nachet type)
This microscope is
unsigned by the maker on the brass-work. It is however
marked in ink on the bottom of the leather-covered
base, but
the signature is indistinct. Some early French drum
microscopes of this design are known that, while not
exactly identical to the instrument shown here, are
signed by Camille Sébastien Nachet (1799-1881). One
such example is located this collection.
Similar microscopes are also known that are either
unsigned or are signed by other opticians. One closely
resembling this microscope is located in the Harvard Collection
(inventory Number: 1081a) and is dated
1845-1850; while it is also unsigned, it is attributed
to Nachet.
Another microscope very similar to the one shown on
this page, but slightly larger is also in this
collection.
The microscope is
supplied with a full compliment of accessories which
include two eyepieces, three triple button objectives
two of which have their own nosepiece, a brass trough
with glass bottom for wet preparations, a camera
ludica, a stage condenser on an articulated arm, two
glass slips with brass clips (an early form of live
box/compressor), an ivory and ebony stage disk for mounting opaque
objects, and a set of dissection tools.
Stamped in ink on the
inside lid of the case is a name and address, Werner U.
Pieper, Heidelberg, Schafergasse 69, possibly that of a
prevous owner.
