Leonard Cline

Leonard Lanson Cline (1893–1929) was an American novelist, poet, short story writer, and journalist.

In 1927 he published The Dark Chamber, arguably his most famous work. It was described by H. P. Lovecraft in his Supernatural Horror in Literature as "extremely high in artistic stature". A review proclaimed, "he has opened a squamous dungeon of the mind and explored it with the erudite perversity of a cheerier, juicier Poe. Like all horror stories it is belittled by its own theatricality yet it remains an amazingly worded orgy of the more unspeakable human propensities."

He also published stories in the pulp magazines under the pseudonym "Alan Forsyth". (Six of these stories are collected in The Lady of Frozen Death and Other Weird Tales, published in 1992).
