by Geoffrey Mortimer
Born in 1861, Walter Matthew Gallichan was a British journalist and author from Jersey who sometimes wrote fiction as Geoffrey Mortimer. Records from Victorian fiction databases identify Geoffrey Mortimer as a pseudonym and describe him as an active novelist as well as a journalist.
He published novels including Like Stars that Fall and Tales from the Western Moors in 1895. He was also connected to the novelist Catherine Gasquoine Hartley, whom he married in 1901; accounts note that after their marriage he wrote under his own name rather than the Geoffrey Mortimer pseudonym.
Gallichan died in 1946. Although he is not widely remembered today, his career reflects the flexible, fast-moving literary culture of his time, when writers often worked across journalism, fiction, and other forms of popular nonfiction.
