The Norwegian physicist Lars Vegard is primarily remembered for his contributions to the physics of the Northern Lights and in particular his exploration of their optical spectra. He is remembered in theVegard-Kaplan band, forbidden emission by nitrogen molecules between 2340 and4324 angstroms, seen first in aurorae and later in laboratory experiments and in the Martian dayglow.

Lars Vegard grew up under modest conditions in a ruralpart of southern Norway.He was the youngest of seven children of the farmer Nils Gundersen and his wifeAnne. He married Inger Hervora Petersen in 1915. The couple had a daughter.

In the years 1899–1905, Vegard studied science at the Oslo University and there after worked as an assistant for Kristian Birkeland. From 1909 he was employed by the university, appointed associate professor 1915, and finally made full professor in 1918 succeeding to the chair of Birkeland.
