1882–1960
Best known for fast-moving mystery and detective fiction, this early 20th-century novelist wrote a long run of crime stories, including the Gray Phantom books. His work appeared mainly in the 1920s and 1930s and still turns up in reprints of vintage pulp-era suspense.

Herman Landon (1882–1960) was an American author of mystery and detective fiction. Surviving catalog records link him to a substantial body of popular crime novels, with titles such as The Gray Phantom, The Gray Phantom's Return, Hands Unseen, The Forbidden Door, and The Back-Seat Murder.
His books fit squarely into the pulp-era appetite for masked figures, hidden identities, locked rooms, and fast, twisty plotting. The recurring Gray Phantom stories are the best-known part of his output and give a good sense of his style: brisk, dramatic, and built to keep readers guessing.
Reliable biographical detail on his personal life appears to be scarce in the sources I could confirm, so it is safest to remember him primarily through the work itself. For readers who enjoy vintage crime fiction, Landon offers a lively snapshot of popular suspense writing between the world wars.
