Olle Elmgren (1894-1985) was a lighting architect at Nordiska Kompaniet from 1923 until his retirement in the 1960s. He worked alongside Erik Tidstrand and Bertil Brisborg and played a significant role in the development of NK's lighting fixtures. Elmgren is best known for his interior projects within churches and cinemas, but he also left his mark on prestigious projects such as the interior design of M/S Kungsholm and Ivar Kreuger's bank palace in Paris, as well as the creation of fixtures for the Stockholm Exhibition in 1930. Despite his long career, Elmgren is rarely mentioned for his designs. In depictions of Nordiska Kompaniet, he is typically portrayed as a reserved individual who primarily operated behind the scenes.
