H. F. Cente

Writing under the better-known name Ross Rocklynne, this American science fiction author was born Ross Louis Rocklin in Cincinnati, Ohio, on February 21, 1913, and died in Los Angeles on October 29, 1988. He was active during the Golden Age of science fiction and also used other pen names, including Paul Cahendon, R. L. Rocklin, and R. Rocklinne.

He became a science fiction fan early in life and later turned that enthusiasm into a long pulp-magazine career. He sold his first story, Man of Iron, to Astounding Stories in 1935, and went on to contribute regularly to magazines including Astounding Stories, Fantastic Adventures, and Planet Stories.

The byline H. F. Cente is attached to Sales Talk, a novella published in Planet Stories in July 1953 and later preserved by Project Gutenberg. While detailed biographical information specifically under that byline is scarce, the story fits naturally alongside the lively, imaginative magazine science fiction of Rocklynne's era.
