Microscope
272 (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
272 is a simple compound microscope of French origin dated to c. 1900. The
focus in this microscope is controlled by a knob and the tube contains an
eyepiece and a lens formed by two lenses set in brass rings screwed onto each
other (typical French design). 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.
