author
Best known for the science-fiction story Captain Chaos, this pulp-era writer is a fairly elusive figure today. The surviving record points to a short, energetic space adventure first published in the early 1950s and later preserved online for new readers.

by D. Allen Morrissey
D. Allen Morrissey is a little-documented science-fiction author whose name survives mainly through Captain Chaos. Project Gutenberg and major bookselling catalogs list that title as the work most clearly associated with Morrissey, suggesting a small known bibliography rather than a long, widely documented career.
The available record indicates that Captain Chaos originally appeared in Planet Stories in November 1952. The story was later made available by Project Gutenberg in 2020, helping keep Morrissey's work accessible to modern readers.
Because reliable biographical information is scarce, not much more can be confirmed with confidence about Morrissey's life beyond the publication history of that story. Even so, Captain Chaos places the author within the lively mid-century magazine tradition of fast-moving, imaginative science fiction.
