Description

This microscope was produced by the Parisian optician Louis Joseph Deleuil (1795-1862), according to specifications suggested by François-Vincent Raspail (1794–1878), as a modified version of the Cuff/Ellis type aquatic microscope. In the literature, it is said to have tourmaline lenses for high magnifications (to reduce aberrations as tourmaline has an extremely high refractive index). Still, my examination of at least the high magnification in this instrument proved it untrue.

This successful design of a portable single microscope was planned by François-Vincent Raspail (1794–1878, picture below with his microscope), a political reformer and activist and a prominent early 19th-century scientist. Raspail (seen in the photo with this type of microscope) was a founder of microscopical methods in chemistry, a pioneer of organic chemistry and one of the first founders of the cell theory in biology. Raspail also pioneered the staining methods in cell biology using iodine to highlight their different parts. As a politician, Raspail was a devoted republican who was active during the restless periods of the First Empire, the Restoration, the Second Republic and the Second Empire, for which he was sentenced several times to prison.

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.
