Microscope
446 (Carl Zeiss; binocular
stand XB; c. 1912) In 1846, Carl Zeiss opened a workshop
for precision mechanics and optical instruments in Jena. He focused his
activities more and more on microscope production. Soon he was supplying not
only the regional market but also shipping his wares around the world. In
1866, Carl Zeiss recruited the physicist Ernst Abbe to help him improve his
microscopes. In 1877, Ernst Abbe became a partner in the company. After the
passing of Carl Zeiss in 1889, Ernst Abbe created the Carl Zeiss Foundation,
which would become the company’s sole owner. Since the 1890s, Abbe’s findings
and his style of working have also been adopted in other fields of optics.
This led to the creation of all-new products, new business areas and rapid
growth for the company. In 1893, the first subsidiary was opened in London.
Before the outbreak of WWI, sites were established across the world, which
then had to be closed when war broke out. There were more ups and downs
between then and 1945. Thereafter, the sites outside Germany have been
developing in a stable manner and today, Carl Zeiss AG is a holding company
with several subsidiaries. In addition to its sites in Oberkochen
and Jena, its main production sites are in Wetzlar
and Göttingen in Germany, Dublin and Minneapolis in the US, and Shanghai in
China. Microscope 446 is engraved on the binocular head with “CARL ZEISS,
JENA”, the serial number 54348, and should be dated to c. 1912. This
instrument corresponds to the Zeiss’s binocular stand XB (Figure 1). The
microscope is also engraved on the base and binocular head with the inscription
“BRIT. MUS. N.H., Z.D.5”, suggesting that this instrument belonged to the
British Museum in London at some point in history. The original wooden box of
the instrument is also engraved with “Mr. Robson’s Rm., 5”, potentially
associating this instrument with Guy Coburn Robson (1888 – 1945), who was a
British zoologist, specializing in Mollusca, who first named and described Mesonychoteuthis hamiltoni,
the colossal squid. Robson studied at the marine biological station in Naples, and joined the staff of the Natural History Museum
in 1911, becoming Deputy Keeper of the Zoology Department from 1931 to 1936. Robson
is also best known for his major co-authored book The Variations of
Animals in Nature (1936), which argued that although the fact of
evolution is well established, the mechanisms are largely hypothetical and
undemonstrated. Note: this instrument was kindly
donated by Dave Levell (Pembrokeshire, Wales) in May 2023. Figure 1. Carl Zeiss’s binocular stand XB as featured
