by J. M. W. (Jacob Mortimer Wier) Silver
Born Jacob Mortimer Wier Silver in 1887, he was an American author who published mainly as J. M. W. Silver. Reliable reference sources identify him as a prolific writer of mystery, science fiction, and western stories, active during the early-to-mid 20th century.
He also wrote under other names, including James M. Wier Silver and Gerald Vance. That range of bylines fits the kind of career many pulp and popular-fiction writers built at the time, moving between genres and markets while producing work steadily for magazines and books.
Silver died in 1971. While detailed biographical material appears limited in the sources I could confirm, the record that does survive points to a versatile professional storyteller whose work reached readers in several corners of popular fiction.
