by Seabury Quinn
Born in Washington, D.C., Seabury Grandin Quinn (January 1, 1889–December 24, 1969) was an American lawyer, journalist, and pulp-fiction author. He studied law at National University and also built expertise in mortuary law, an unusual professional background that gave some of his fiction its memorable detail and atmosphere.
Quinn is remembered above all for his long-running series about Jules de Grandin, an occult detective who appeared again and again in Weird Tales. Those stories made him one of the magazine's most popular contributors and helped shape the feel of classic American weird fiction between the 1920s and mid-20th century.
Although readers today often discover him through horror and supernatural anthologies, his appeal came from his knack for clear storytelling, colorful shocks, and energetic plot twists. His work stands as a vivid link to the golden age of pulp magazines, when strange fiction was serialized for an eager mass audience.
