The fellow with the round glasses is and a moustache, is physics professor Kristian Birkeland. While working on an electric cannon he had invented, he came up with a theory that could explain the northern lights (stella borealis). The photographer himself and professor Birkeland went on expeditions together in the arctic parts of norway. Few believed in Birkeland’s theories, until modern satelites proved he was actually right and it’s electromagnetic. To me it seems like some of the young women liked the photographer. Some of my ancestors lived in Oslo at that time, and could be present in some of the photos. As an inhabitant of Oslo myself, these photos are a real gem.
