dc.description.abstract	This early instrument, with a horseshoe-shaped base, has a brass body-tube that moves on the rackwork and is attached to the limb by a short arm. The pillar supports the stage and the limb. The instrument is also fitted with an Abbe condenser and an iris diaphragm, features which were added later on. Based on the style and the low serial number, however, we believe that the microscope dates from about 1860. No carrying case or accessories. Signed on the tube: Oberhaeuser, Place Dauphine, Paris. Stamped on the bottom of the base: 2247.

dc.relation.ispartof	Born in Germany, Oberhaeuser moved to Paris in 1818, after having served his apprenticeship in Wurzburg. In 1822, he started his business, and worked with Trecourt and Bouquet from 1830 to 1835. In 1857, his nephew, Edmund Hartnack (1826-1891), joined the firm. Oberhaeuser enjoyed a reputation as a major instrument maker.
