author
Best known for a single burst of pulp-era imagination, this elusive science fiction writer is credited with co-authoring the 1942 Mars adventure Meteor-Men of Mars. Very little biographical information appears to have survived, which only adds to the mystery around the name.

by Harry Cord, Otis Adelbert Kline
Harry Cord is a very obscure figure in science fiction history. Reliable bibliographic sources consistently credit the name to Meteor-Men of Mars, a novelette published in Planet Stories in Winter 1942 and co-written with Otis Adelbert Kline.
Beyond that publication record, solid personal details are hard to confirm. Major book and bibliography databases list the work, and Project Gutenberg preserves the text, but I could not verify basic biographical facts such as birth and death dates, nationality, or a fuller career.
That makes Cord one of those intriguing pulp-era bylines who survives mainly through the story itself. For readers, the appeal is in that glimpse of early magazine science fiction: fast-moving, planetary, and full of the wide-screen sense of adventure that defined the genre's classic pulp years.
