This type of simple field microscope was invented by Benjamin Martin, an English scientific instrument maker in the middle of the 18th century. Martin is believed to have produced several versions of this type of microscope between the 1750s and his death in 1782. In the mid-19th century the drum microscope was popularized by the instrument maker Georg Oberhausser, who was based in Paris from the 1830s. These microscopes would typicaly have been used in the field by amateur geologists, botanists and other scientists.
