Microscope 306 (W & H Seibert, student
microscope, 1910s) Wilhelm
and Heinrich Seibert were brothers who worked for Carl Kellner’s optical
business in the 1850s, in Wetzlar, together with Ernst
Gundlach. In 1859, Gundlach started his own microscope manufacturing firm,
and the Seibert brothers also joined this company as employees. This company
entered in debt and Gundlach left for England in 1860. Later, in 1865,
Gundlach returned and, this time in Berlin, he started a new optical firm to
which the Seibert brothers also joined in about 1866. In 1872, the Seibert
brothers joined Georg Krafft and bought the firm
from Gundlach, and he emigrated to the USA. The firm moved to Wetzlar and was initially named Seibert & Krafft (1871 – 1884). In 1884, the firm changed the name
to W & H Seibert and operated until c. 1925. Microscope 306 is
engraved with ‘Seibert in Wetzlar’ and the
serial number 15112. The instrument is a student microscope and should be
dated to the 1910s. Seibert’s student microscope as engraved in
