John Martin Leahy (1886–1967) was an American author and illustrator who made significant contributions to early twentieth-century speculative fiction. Operating within the vibrant world of pulp magazines, Leahy was a versatile creator who not only penned tales of the strange and unusual but also provided the illustrations for his own works. His stories and artwork found a home in influential publications of the era, most notably Weird Tales and Science and Invention, where he helped establish the aesthetic of early science fiction and horror.
Among his most notable literary achievements is the 1928 short story "In Amundsen’s Tent." This work is highly regarded by genre historians as an important precursor to seminal works of science fiction and horror, anticipating the themes of H. P. Lovecraft’s novella At the Mountains of Madness and John W. Campbell Jr.’s "Who Goes There?". Decades later, Leahy's novel Drome was published in book form by the Fantasy Publishing Company, Inc. in 1952, preserving his imaginative vision for subsequent generations of readers.
