Leslie F. (Leslie Francis) Stone

Born in Philadelphia in 1905, Leslie F. Stone wrote under a pen name that masked her identity in a magazine world that often assumed science fiction was for men. She became one of the first women to make a real mark in the pulp science fiction magazines, publishing more than twenty stories between 1929 and 1940.

Her work appeared in major genre magazines of the day, and she is especially remembered for energetic, idea-driven stories that pushed beyond the usual formulas. Modern readers and critics often note how her fiction made space for female protagonists and other perspectives that were uncommon in early pulp science fiction.

Stone was born Leslie Frances Rubenstein and later became Leslie Frances Silberberg after her marriage. She died in Philadelphia in 1991, but her reputation has continued to grow as historians of science fiction have looked more closely at the women who helped shape the field from the start.
