by Aarne Mustasalo
Born as Heikki Eliel Nurmio in 1887 and later known to readers as Aarne Mustasalo, he was a Finnish jäger, military officer, war historian, and writer. Finnish and English Wikipedia entries both identify Aarne Mustasalo as Nurmio’s pen name, and note that he lived from 1887 to 1947.
Alongside his military career, he wrote fiction for younger readers. Library and book sources connect the Mustasalo name especially with the Jokikylän pojat books, while Project Gutenberg lists works including Jääkärin päiväkirja, showing the range from youth literature to writing shaped by military history and the Finnish independence era.
He is also widely remembered in Finland for writing the words to "Jääkärien marssi", with music by Jean Sibelius. That mix of soldier, historian, and storyteller helps explain why books published under the name Aarne Mustasalo carry both a sense of adventure and a strong link to Finnish national history.
