With his name printed as "D.M. Fried. Möller" on ornately-designed labels, this professional slide-maker was a younger brother of the celebrated diatom mounter Johann D. Möller (1844-1907).

J.D. Möller established his workshop in Wedel, Holstein (Germany) in 1864, producing optical lenses, polarizing apparatus, magic lantern slides, and a variety of microscope slides. By the end of that decade, he had become internationally renowned for his slides of arranged diatoms.

A history of J.D. Möller states, "Das Geschäft lief so gut, dass bald seine Brüder Dittmer und Simon, sowie zeitweise auch sein Stiefbruder Albert mitgearbeitet haben" ("The business went so well that his brothers Dittmer and Simon, and briefly his step-brother Albert, worked together").

Microscope slides by D.F. Möller are relatively scarce, and his arranged diatoms slides are even more so (Figures 1 and 2). An 1883 advertisement has been identified, which appeared in the German nature magazine Isis (Figure 3). It is no known how much longer D.F. Möller continued with his slide-making business, or what other professions he pursued. He was included in a 1905 family photograph that was taken at his nephew's wedding (that being Hugo Möller, one of J.D. Möller's sons) (Figure 4).
