Georg Michael Dødelein Reiss (August 12, 1861 – January 25, 1914) was a Norwegian lawyer, composer, and musicologist.

[2][3] Reiss was trained as a lawyer; he received his candidate of law degree in 1886, and he started working as a secretary in the Ministry of Culture and Church Affairs in 1899.

[3] Reiss himself wrote a church cantata in 1902, and other compositions for voice and choir, including an eight-part kyrie.

[1] With support from the Nansen Foundation and as a government scholar starting in 1908, Reiss studied neume notation, paleography, and medieval music theory, published manuscripts from the National Archives, worked on two sequences for Saint Olav, and received a PhD in 1913 with his dissertation Musiken ved den middelalderlige Olavsdyrkelse i Norden (Music in the Medieval Olav Cult in the Nordic Countries), which was Norway's first doctorate in music history.

Georg Reiss married Elisabeth Dymling (1861–1920), a merchant's daughter, in Vänersborg in 1893.
