Wilhelm (1840 - 1925) and Henry (1842 - 1907) Seibert studied optics under Carl Kellner (1826-1855). After Kellner’s early death they worked together with Ernst Gundlach and Edmund Hartnack. After acquiring Gundlach's business in Berlin, they began the production of high-quality microscopes. The No IV model is based on the original design of Ernst Gundlach, who sold his business to Seibert and Krafft before leaving for the United States. The microscope features the "C-limb" and parallel linkage focusing system, typical of several German makers of the end of the 19th century.

Description

The microscope of choice for many researchers: In 1876, Dr. Robert Koch (Nobel Prize in Physiology or Medicine in 1905) purchased a microscope of the IV model seen here for his research of the Anthrax bacteria and photomicrography after advice from his friend and mentor, Ferdinand Julius Cohn (1828-1889). During his work, Koch was involved with many microscope improvements in lighting and resolution and became the first physician to use an oil immersion lens, the Abbe condenser, and photomicrography of bacteria. In his later years, Koch worked with a Zeiss microscope.

Walther Flemming used a Seibert Stativ IV with a second mirror added to illuminate above and below simultaneously for his studies of mitosis. Another microscope of the same model was used by the Danish doctor Hans Christian Gram who developed the staining method called after him. A Seibert microscope of this kind was also employed by August Krogh Bain for his studies of the of the mechanism of regulation of the capillaries in skeletal muscle, for which he was awarded the Nobel Prize in Physiology or Medicine in 1920.

NOTE TO  BUYERS: Due to vocation, the microscope will be sent on September 1st. My apologies for any inconvenience.

IL Gilgamesh

Gilgamesh was the mythological hero of the cultures of ancient West Asia, who set out on a journey in which he sought youth and eternal life.
Fleaglass Gilgamesh is located in Israel. As an archaeologist researching the material culture of the distant past and using the microscope as a major research tool, for more than two decades I have collected microscopes from the first 300 years of existence of this amazing tool and researched the cultural context of their use. Passion has become an obsession and I cultivate the full and almost unique West Asian collection of historical microscopes. Respectively, I put up for sale surplus or interesting items from the collection. I would be happy to advise any interested collector free of charge. Needless to say, I would love to send photos, information and bibliographic references, and discuss the sale details of the items offered here for sale.
