Microscope 5 (assigned to Deyrolle; c. 1900) The ‘Les fils d'Émile Deyrolle’, which traded from 1831 to 2003, was originally
founded by Jean-Baptiste Deyrolle in Paris, France.
He sold insects for natural history collections, and the business was passed
down in the family and expanded to taxidermy and other natural history
specimens. Four generations after opening the business the heirs changed the
name to "Les Fils d'Émile
Deyrolle” (they had taken over the business by
1896). At some point in history, they traded also optical instruments such as
microscopes and other scientific equipment for the mounting, displaying, and
maintenance and care of natural history specimens and collections. Microscope
5 is a simple compound microscope of French origin and dated to c. 1900. The
sliding tube contains an eyepiece and a lens formed by two lenses set in
brass rings screwed onto each other (typical French design). The focusing is
by manually sliding the tube but versions where the focus is controlled by a
knob are also known. These types of microscopes appear in the catalogues of
several American retailers such as B. Kahn & Son (where the versions with
and without the knob-controlled focus were described respectively as the Challenge
and Amateur models) and Meyrowitz (known as
the ACME microscope model). An identical instrument, with a knob-controlled
focus, is engraved in the
catalogue Micrography of July 1900, edited by the Parisian firm ‘Les Fils d'Émile Deyrolle’ (where it was called microscope a
renversement Modèle D) (Figure
1). Other companies where identical microscopes are featured in their
catalogues are JH Steward, E. Vion, Latour and Derogy. Figure 1. Microscope
