Walter L. Kleine

Walter L. Kleine is a mid-20th-century science-fiction author whose best-known work is Deadline. Project Gutenberg lists him as the author of that novel, and the surviving record around his career appears to be quite slim, which gives his work a certain rediscovered quality.

Deadline was first published in the 1950s and centers on a dangerous early Mars mission, with a small crew forced into impossible decisions under severe time pressure. The novel's premise, practical problem-solving, and survival stakes place it firmly in the tradition of classic magazine-era science fiction.

Beyond that book, reliable biographical details about Kleine are hard to confirm from readily available sources. Rather than overstate what isn't well documented, it's fairest to say he is remembered today mainly through Deadline and its continued appeal to readers who enjoy lean, idea-driven space adventure.
