This microscope dates
from around 1880. The Grunow brothers, Julius and
William, emigrated from Germany to New York around
1849. They started in the scientific instrument
business by first working for the optician Benjamin
Pike of that city. By 1854, they began their own
operation in New Haven CT where they concentrated on
the production of microscopes. By 1864, they were back
in New York. Some years later, the partnership ended.
J. Grunow continued on to produce microscopes up to
around 1892. The total output of the Grunows was
limited in comparison to some other contemporary firms;
on the basis of the observed serial numbers, they
manufactured just over one thousand microscopes in
total.
