1852-1928 was a Norwegian painter. He attended the of Fredrik Eckersberg in Kristiania (now Oslo) in 1866 and 1870. After that, he studied painting briefly with Knud Bergslien at the Johan Fredrick Eckersberg School of Painting and left to go abroad in 1871. He studied at the School of Art of Copenhagen; in Karlsruhe (1871?C1873), where he was a student of Hans Gude; and, together with Hans Heyerdahl, in Munich under Wilhelm von Diez. He then studied in London, Paris, and Italy. After these travels, he returned to Norway and settled in Bærum. He made his debut at the Høstutstillingen (Autumn Exposition) in Kristiania in 1882. He was a profound connoisseur of European art and was later associated groups such as Lysaker, the painters of Fleskum and those of Skagenpainters, as well as with individual artists like August Eiebakke, Kitty Kielland and Harald Oskar Sohlberg. In Norway, he is also known as the designer of the coat of arms of Norway, adopted when the country separated from Sweden in 1905 to become an independent country. This version was used for official government purposes until 1937, when it was replaced by a new version. Nonetheless, Peterssen's design is still used for the royal coat of arms and for the royal flag. In addition to his canvasses, he collaborated on the decoration of the Tourist Hotel in Holmenkollen in 1889. In the same year, he painted the murals "The Wanderers of Emmaus" in the Church of Tanum in Bærum and "Jesus in the Garden of Gethsemane" in the Church of the Cross, Bergen.
