Ragnvald Tønsager

Oct. 18, 1888 in Oslo, Norway
Dec. 2, 1964

Ragnvald Tønsager was a Norwegian architect.

He established his own architectural firm in Oslo in 1921 and over four decades, he designed numerous residential, office, and industrial buildings in Oslo. During the same period, he also served as a teacher at the Oslo Elementary Technical Evening School. Stylistically, Tønsager, like many architects of his time, transitioned from neoclassicism to functionalism.
