Sir Ronald Ross (1857 – 1932) was a British doctor who received the Nobel Prize for Medicine in 1902 for his work on malaria. His discovery of the malarial parasite in the gastrointestinal tract of the Anopheles mosquito led to the realization that malaria was transmitted by Anopheles, and laid the foundation for combating the disease.

The microscope designed by Dr. Ross and sold by Baker from 1893 to the turn of the century had a fine focus in the exact location as the previous Moginie-style microscope, at the top of the back support. The from seen here is a slightly later successor to that designed by Dr. Ross, having a considerably more straightforward to use  coarse focusing knobs operating a rack and pinion mechanism. This instrument combines Dr. M.C. Cooke’s Design for a modified Moginie, Dr. Ross’s design for a Malaria microscope, and likely Baker’s “Histological Microscope” of 1885.

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.
