This travel microscope was developed under the Viennese company of Reichert by Kurt Friedrich Reinsch (1895-1927), a German hydrobiologist and designer of microscopes. Reinsch studied zoology at the Ludwig-Maximilians-Universität in 1912. During the First World War he served as a volunteer in the Prussian Telegraph Battalion No. 2. In 1922, Reinsch completed his doctorate on "The entomostrake fauna in its relationship to the macro flora of the ponds" and subsequently undertook research at the experimental station of Reinhard Demoll in Munich. After participating in the Biologists Congress in Innsbruck, he stayed in Austria and took up residence in Vienna . There he worked as an assistant to Oskar Haempel at the Department of Hydrobiology and Fisheries Economics of the College of Agricultural Sciences. In 1925, Reinsch received a research contract from the Icelandic agricultural company Bunadarfjelag for the biological study of the freshwater areas of the island state. After returning to Vienna, he began working with the Viennese microscope factory C. Reichert on the development of the Heimdal small field microscope for wartime use. In 1927, Reichert launched the "Field Microscope Heimdall after Reinsch" on the market. In the same year, the biologist patented the "microscope with continuously adjustable aperture".

Reinsch died in 1927 at the age of 31 after surgery in Munich from a cancer.

In 1929 the Japanese Tiyoda microscopes of Tokyo (now Sakura Finetek Japan Co., Ltd.) copied the Heimdal in a slightly simplified manner under the name Tioyda MKH or "Mkatera Portable", mainly for the army or animal doctors. It is unclear whether this imitation was allowed by Reichert.  During World War II this model was used by the Imperial Japanese Army as the standard microscope for the field hospitals in the frontlines. The example at the bottom of this page, previously in this collection, was acquired from a WWII veteran who served in the Pacific front and took it as war booty.
