Otto Engb. (Otto Engelbert) Jaatinen

Born in Viipuri on November 7, 1881, Otto Wilhelm Engelbrekt Jaatinen built a varied career in business and administration. Finnish biographical sources describe him as a stockbroker, managing director of Kauppalehti Oy, and later the director of the Port of Helsinki.

Alongside that work, he wrote plays under the pen name Otto Vilho. His known dramatic work includes Kuninkaan tuomio (1908), showing that his literary interests ran in parallel with his professional life rather than apart from it.

Jaatinen died on June 25, 1934, in Helsinki. Though not remembered primarily as a full-time literary figure, he stands out as one of those early 20th-century writers whose creative work grew out of a much broader life in Finnish civic and business circles.
