Roger T. (Roger Thompson) Finlay

Roger T. Finlay, also listed as Roger Thompson Finlay and born in 1860, was an American writer associated with adventure fiction for young readers. His name appears on a run of books published in the 1910s, especially the Wonder Island Boys series, which mixes castaway survival, invention, travel, and encounters with island communities.

Library and public-domain records confirm several titles in the series, including Exploring the Island, Adventures on Strange Islands, and Treasures of the Islands. The stories were published by The New York Book Company and later preserved through collections such as the Library of Congress and Project Gutenberg, which helped keep his work available to modern readers.

Beyond those publication details, biographical information about Finlay is scarce. The Encyclopedia of Science Fiction even notes that he may have been a pseudonym, so it is safest to treat him as a somewhat shadowy figure whose reputation rests mainly on the lively, fast-moving adventures published under his name.
