Hallvard Trætteberg

Hallvard Trætteberg (21 April 1898 in Løten Municipality – 21 November 1987 in Oslo) was the leading Norwegian heraldic artist and the expert adviser on heraldry to the Government of Norway and the Norwegian royal family for much of the 20th century. From about 1930 he played a central role in the renewal of public heraldry in Norway with an emphasis on simplification. He gave the coat of arms of Norway a modern design and designed several county and municipal coats of arms, seals of the bishops of the Church of Norway, and monograms. He also wrote several books.

He was a Knight First Class of the Order of St. Olav and a member of L'Académie Internationale d'Héraldique. He was employed at the National Archives of Norway from 1924. Trætteberg was the acting national archivist of Norway from 1963 to 1964. Provided by Wikipedia
