William Anthony Parker White, better known by his pen name Anthony Boucher, was an American author, critic, and editor who wrote several classic mystery novels, short stories, science fiction, and radio dramas. Between 1942 and 1947, he acted as reviewer of mostly mystery fiction for the San Francisco Chronicle. In addition to "Anthony Boucher", White also employed the pseudonym "H. H. Holmes", which was the pseudonym of a late-19th-century American serial killer; Boucher would also write light verse and sign it "Herman W. Mudgett".

Jorge Francisco Isidoro Luis Borges Acevedo was an Argentine short-story writer, essayist, poet and translator regarded as a key figure in Spanish-language and international literature. His best-known works, Ficciones (transl. Fictions) and El Aleph, published in the 1940s, are collections of short stories exploring motifs such as dreams, labyrinths, chance, infinity, archives, mirrors, fictional writers and mythology. Borges's works have contributed to philosophical literature and the fantasy genre, and have had a major influence on the magic realist movement in 20th century Latin American literature.
