Which magician received the original byline for 'Imprisoned with the Pharaohs'?

The magician who received the original byline for “Imprisoned with the Pharaohs” was Harry Houdini.

Lovecraft wrote the story in 1924 after Weird Tales founder J. C. Henneberger commissioned it as a fictional account supposedly narrated by Houdini. Because the tale is written in Houdini’s first-person voice and presented as an alleged personal experience in Egypt, the magazine credited Houdini alone in its original publication.

The story follows Houdini on a visit to Egypt in 1910. After being kidnapped by a guide, he is thrown into a cavern near the Great Sphinx, where he encounters an immense subterranean ritual world and a monstrous power behind the Sphinx’s construction. The fantastic events are presented as an escape artist’s claimed memoir.

Lovecraft’s authorship was acknowledged in a later 1939 reprint. The tale is therefore often described as a Lovecraft story written in collaboration with, or ghostwritten for, Houdini—not as a work actually written by Houdini.
