Little is known about Bachmann’s life, but he is included in this series because of a valuable reference book on microscopy that he published in 1883, Unsere Modernen Mikroskope. Notably, Bachmann’s book included dozens of illustrations of commercially-available microscopes of that year. These were primarily of German make. Images extracted from this insightful collection are shown below.
Bachmannn worked as a science teacher in Landsberg am Lech, Bavaria. He was established there before 1875, and was still there in 1905. An image of a microscope slide with Bachman’s labels was illustated in Ziemann’s 1875 Leitfaden für die praktische Mikroskopische Untersuchung des Schweinfleisches auf Trichinen, with a statement of Bachmann having a “Mikroskopisches Laboratorium” (Figure 3). Bachmann was described in 1881 as a “tüchtige Microscopiker und Malacozoolog” (“a capable microscopist and malacozoologist” - malacozoology is the study of molluscs). Entries in The Naturalists’ Universal Directory indicate that he was also interested in lepidoptera and coleoptera. His 1883 entry reads, “Bachmann, Otto, Konigl. Reallehrer, Laboratorium für Mikroskopie, Landsberg am Lech (Bavaria). Con. C. Ex. Wishes to receive shells of any kind in ex. for any Microscopic preparations”.
