Comments Off on Rare Cuff-Styled Microscope by a Dutch maker, ca. 1760
The original Cuff microscope emerged around 1745 and gained significant popularity, largely thanks to the efforts, writings and patronage of Henry Baker. Since the microscope was never patented—a complicated process in the 18th century—numerous copies quickly appeared, made by other English manufacturers as well as by some continental European makers in countries where microscopes were popular, including France, the Netherlands and German Lands. These imitations retained the core concept of Cuff’s design while incorporating local ideas that had already influenced Read More...
