author
An early 20th-century writer whose work captured the grit and adventure of the postal service, he is best known for Postal Riders and Raiders (1912), a lively look at mail carriers and the dangers they faced.

by W. H. Gantz
Very little biographical information about W. H. Gantz could be confirmed from the sources available during this search. What is clear is that he is credited as the author of Postal Riders and Raiders, published in 1912 and associated with the Independent Postal League.
That book focuses on postal workers, routes, and the hazards of carrying the mail, suggesting a strong interest in postal history and the everyday heroism of mail service. Because reliable personal details such as his full name, dates, or background were not readily available in the sources reviewed, it is best to treat him as a somewhat obscure historical author whose reputation rests mainly on this surviving work.
