author
A little-known 19th-century writer linked to adventure fiction about emigration and survival in Australia. Only a small amount of biographical information is easy to confirm, which gives the work an air of mystery as well as historical interest.

by Karl Listner, Friedrich Gerstäcker
Karl Listner appears in public-domain library records as an author associated with Siirtolaisen elämän vaiheet; Haaksirikon jälkeen: Kaksi kertomusta Austraaliasta, a Finnish edition published in 1875. In Project Gutenberg's catalog, he is listed alongside Friedrich Gerstäcker, suggesting a connection to German-language adventure storytelling and themes of travel, danger, and starting over in a distant land.
The surviving book record points to stories about immigrants, sea travel, shipwreck, and life in Australia. That places his work in the lively 19th-century tradition of fiction shaped by migration, colonial frontiers, and endurance under pressure.
Beyond that, reliably confirmed personal details about his life are scarce in the sources I could find during this search. No clear, verified portrait turned up either, so the focus remains on the atmosphere of the writing itself and on the small but intriguing trace he left in historical book catalogs.
