author
A little-known French writer whose work survives through a rare science-fiction short story, with just enough mystery around him to make the name memorable.
Adrien Coblentz appears to be a very obscure author, and only a small amount of reliable biographical information is easy to confirm. Public records available through reference and library-style sources identify him as a French figure born in 1866 and deceased in 1928.
His name is attached to The Perverse Erse, a short story later preserved by Project Gutenberg from a 1960 magazine appearance. Because the surviving documentation is so thin, it is hard to say much more with confidence about his literary career.
That scarcity gives him an unusual place in older speculative fiction: not a widely documented literary personality, but a nearly forgotten name kept alive by a single intriguing story and a faint paper trail.
