Christmas lecture “Fred Enock’s sketches”

Brian Davidson gave another of his well-researched lectures, this time illustrated with several slides from his collection. In the 1880s, a number of Victorian slide makers tried to generate a regular income by producing a series of slides accompanied by notes, sketches and photomicrographs to which customers could subscribe. Fred Enock (1845–1916) was a skilled mounter with poor business skills, but he produced a set of 22 slides with accompanying materials. He used to collect specimens in the summer, and spend the winter mounting and lecturing. Six months ago, Brian was given a set of copies of the sketches, and managed to find matching slides for most of them in his collection, and he showed us all of the notes and slides. Enock also produced illustrations for a number of books. For subjects that needed a black background, he prepared a drawing on white, then cut it out and pasted it onto black gouache.
