Agnar Johannes Barth (26 August 1871 – 4 May 1948) was a Norwegian forester.
He was born in Lillehammer as the son of Jacob Bøckmann Barth.
Described as his "country's leading authority on forestry for many years", he was a professor at the Norwegian College of Agriculture from 1921, and served as rector (roughly, the president) there from 1928 to 1933.
[1][2] Barth was a reserve officer in the Norwegian Army, attaining the rank of Second Lieutenant in 1891.
[3] In one of his first immatriculation speeches, in 1929, he praised the youth in general, and especially the youth who "has created Mussolini's Italy while struggling against corrupted radicalism and communism; an Italian country, which from an essentially impoverished state, standing on the brink of cultural and material collapse, in the course of a few years have been brought fourth to a blossoming state, where the entire people, united and purposeful, with incredible intensity labour for the country's progress".
