Albert Elger was a professional slide-maker, specializing in mounts of arranged diatoms, radiolaria, and other such materials. He is reported to have learned those skills when working for Eduard Thum (1847-1926), in Leipzig, Germany. He then moved on to work as a mounter for the J.D. Möller Optical Works, in Wedel. By 1933, he was operating his own slide-making business in Eutin. His daughter, Anke Korth, is reported to have begun preparing slides professionally in 1983.

I have found only a few details about the lives of Albert Elger and Anke Korth. I would welcome receipt of any additional information, which will be added to this essay with appropriate acknowledgements.
