Victor Gollancz Ltd was a major British book publishing house of the twentieth century and continues to publish science fiction and fantasy titles as an imprint of Orion Publishing Group. Gollancz was founded in 1927 by Victor Gollancz, and specialised in the publication of high-quality literature, nonfiction, and popular fiction, including crime, detective, mystery, thriller, and science fiction. Upon Gollancz's death in 1967, ownership passed to his daughter, Livia, who in 1989 sold it to Houghton Mifflin. Three years later in October 1992, Houghton Mifflin sold Gollancz to the publishing house Cassell & Co. Cassell and its parent company Orion Publishing Group were acquired by Hachette in 1996, and in December 1998 the merged Orion/Cassell group turned Gollancz into its science fiction/fantasy imprint.
