Sigurd Einbu

Sigurd Einbu (November 5, 1866 – May 10, 1946) (spelled Enebue at birth), was a Norwegian self-taught astronomer from Lesjaskog, known to have discovered a nova in the stellar constellation Gemini on March 12, 1912. The nova was named Nova Geminorum 2. Also in 1912 he introduced a new class of variable stars, the RV Tauri variable stars. He spelled his family name Enebo during large parts of his scientific career, but in 1926 he changed it to Einbu according to the local pronunciation.

Einbu attended Hamar offentlige lærerskole, and worked as a teacher in Øyer, Vågå and Sel before returning to his home community Dombås. He took an interest in astronomy at an early age, but could not devote himself fully to astronomy until he was appointedstatsstipendiat (Government scholar) in 1908. He was a founding member of Norsk Novaselskap. He established and ran a magnetic monitoring station at Dombås from 1916.

During his lifetime he was a people's educator and wrote frequently in newspapers and popular journals.

His childhood house Einbustugu has been moved from Lesjaskog to Dombås, and is today a museum in his memory.
