John Mastin

Born in 1865 and dying in 1932, John Mastin was an English author remembered for writing scientific romances as well as nonfiction. Reliable reference sources describe him as a clergyman and science popularizer, and they credit him with three speculative novels, including The Stolen Planet and Through the Sun in an Airship.

Mastin also wrote practical science-based work outside fiction. Catalog and library sources link him to The Chemistry, Properties and Tests of Precious Stones, showing the same interest in explaining technical subjects clearly for general readers.

Although biographical details are not widely documented online, the surviving record suggests a writer with unusually broad interests, combining religion, science, and imaginative storytelling in a way that feels very characteristic of early twentieth-century popular literature.
