Microscope
19 (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 19 is a simple compound
microscope of French origin 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.
