Unknown Microphotograph Maker "GLJ"

by Brian Stevenson
last updated May, 2024

This as-yet unidentified maker of microphotograph slides identified him(?)self with the gothic-print initials "GLJ" (although they may be "CLJ"). Known labels are either gray with the subject title in script font, or yellow with block font. One slide is known that carries a very unusual, handwritten label.

It has been suggested that GLJ was George Jackson (1792-1861), since Jackson is known to have produced microphotograph slides of his colleagues in the Microscopical Society of London/Royal Microscopical Society. However, there are no records to indicate that Jackson had a middle name, or commercially produced microphotograph slides.

Any information on this maker’s identity, or other examples of GLJ’s work, will be greatly appreciated.
