Seabury Grandin Quinn (also known as Jerome Burke; 1889 - 1969) was an American pulp magazine author, most famous for his stories of the occult detective Jules de Grandin, published in Weird Tales. His first published work was "The Law of the Movies", in The Motion Picture Magazine, December 1917. (His story "Painted Gold" may have been written earlier.) "Demons of the Night" was published in Detective Story Magazine on March 19, 1918, followed by "Was She Mad?" on March 25, 1918. He published "The Stone Image" in 1919. He introduced Jules de Grandin as a character in 1925 (taking the character's surname from his own middle name) and continued writing stories about him until 1951. The longest of the de Grandin stories is the 1932 novel-length story The Devil's Bride, strongly influenced by Robert W. Chambers' 1920 novel The Slayer of Souls.
