1877–1947
A doctor by profession and a pulp storyteller by passion, this early fantasy and science-fiction writer helped shape the adventurous "sword and planet" tradition. He is best remembered for the Jason Croft tales and for the many stories he wrote with Junius B. Smith.

Born in Ohio in 1877, John Ulrich Giesy built a career that mixed medicine and popular fiction. He was a physician who later practiced in Salt Lake City, Utah, while also publishing a large body of adventure, fantasy, and science-fiction stories under the name J. U. Giesy.
He is especially associated with the early sword and planet style of fiction, a branch of imaginative adventure that sends earthly heroes into strange worlds. His best-known work is the Jason Croft series, set on the distant world of Palos, and he also collaborated frequently with writer Junius B. Smith.
Giesy's fiction appeared in the pulp-magazine world that introduced many readers to fast-moving tales of mystery, romance, and the fantastic. He died in 1947, but his work still has a place in the history of early popular fantasy and science fiction.
