Nuremberg-type microscopes were manufactured in the toy district of Germany (near Nuremberg) from the late 18th through the middle of the 19th Century. This area produced a large number of instruments, thus there are numerous examples in instrument collections around the world. Clay and Court (1932), described a “Nurrenberg” Culpeper-type instrument used by Ehrenberg (dated around 1820). There were two instruments in the Nachet Collection, both dated “…end of the eighteenth century or the beginning of the nineteenth century.” The Museum Boerhaave has eight Culpeper-type and five sentry-box-type instruments, all dated 1800–1850. Turner (1989) describes three Nuremberg microscopes, dated “1/2 19th C”. The Museo di Storia Della Scienza in Florence has two (dated “1/2 19th C”), and the Billings Collection has nine (all dated earlier). There were four styles: Culpeper-type, Sentry box-type, Solar, and Side Pillar-type. Interestingly, for such a large population all instruments look virtually identical with only minor variations in the decorations.
