Seabury Grandin Quinn (1889–1969) was an American lawyer, journalist, and prolific author of pulp fiction. While he maintained a professional career in government law and edited trade journals, he became one of the most popular and frequent contributors to the seminal pulp magazine Weird Tales during its golden age. Writing under his own name as well as the pseudonym Jerome Burke, Quinn crafted a diverse body of work that spanned horror, fantasy, and weird fiction.
Quinn is most celebrated for creating Jules de Grandin, a French occult detective who, along with his associate Dr. Trowbridge, investigated supernatural phenomena. The de Grandin stories, which blended elements of traditional detective fiction with Gothic horror and the macabre, became immensely popular with readers, outshining many of his contemporaries in terms of sheer volume and fan reception during the magazine's run.
Throughout his literary career, Quinn's work helped define the conventions of the occult detective subgenre. His stories frequently featured encounters with ghosts, werewolves, mad scientists, and ancient curses, all resolved through de Grandin's combination of scientific reason and esoteric knowledge. Today, Quinn is remembered as a foundational figure of the early American pulp era.
