William Anthony Parker White known by his pen-name Anthony Boucher (; August 21, 1911 – April 29, 1968), 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" (another of the murderer's aliases).
