Roger T. (Roger Thompson) Finlay

Roger T. Finlay, also listed as Roger Thompson Finlay, was an American author born in 1860. Surviving catalog and reference records connect him most clearly with popular adventure fiction for younger readers in the 1910s.

He is chiefly known for the Wonder Island Boys series, published in 1914 and 1915. The books follow castaway adventures and island explorations, with recurring themes of resourcefulness, courage, and curiosity about how things work.

Very little biographical detail appears to be widely documented online, but his fiction has remained accessible through library records, public-domain editions, and genre reference sources. That lasting availability suggests a writer whose imaginative, lesson-filled adventures continued to interest readers well beyond their original era.
