by Tatu Valkonen
Born in Vyborg on December 7, 1885, Ilmo Kalervo Taavetti Lassila wrote under the name Tatu Valkonen. Alongside his literary work, he built a distinguished academic career in forestry and became a professor of forest technology at the University of Helsinki.
His writing is remembered especially for its humorous pieces and reflective sketches. Sources describe him as an excellent stylist whose columns and books looked at contemporary life with a gentle but observant sense of irony.
He died in Helsinki on April 27, 1945. For readers coming to him today, Tatu Valkonen offers a mix of intelligence, lived experience, and quietly charming humor.
