This is an example of
the small sized model 3a produced by the firm. See:
Fr. Belthle, Nachfolger von C. Kellner, in Wetzlar
- Price
list for 1866.
Represented in this collection is
another example of this model having a
different selection of optics and a different
layout within the wood storage case.
A search of the
production archives retained by Leica Microsystems
GmbH of microscopes made in the early period of the
Optical Institute in Wetzlar indicates that this
Belthle microscope with serial number 829 is Stand
3 and was delivered to Friedrich Kempf in
Meissenheim on April 21, 1866. It cost 50
Thaler.
At some point in its
history, this microscope had made its way into the
United States of America. It was purchased for this
collection in the US and found within the case was
an old prescription written by a
Dr. E. G. Merwin mentioning Philibert's Pharmacy,
which was located in St. Louis MO. In addition, the
outside of the case bears a round label with the
initials SLU (St. Louis University)
There was a Friedrich Kempf born in Meisenheim, Hessen, Germany on 11 Mar 1844. He died on 24 Oct 1930 in Highland, Madison, Illinois (located right across the river is the SLU campus). Possibly, he is the person who originally purchased this microscope.

Mappes and Rolf Beck of Leica Microsystems GmbH for
