Trefall was born in Bergen on 10 November 1925. He graduated with a degree in mathematics and natural sciences at the University of Bergen in 1951, with an average of 1.21 or "exceptionally well". He became amanuensis at the same university in 1955, docent of physics in 1957, and was appointed professor of experimental physics from 1 April 1964. He obtained a Ph.D. from the University of Oslo in 1961 for six dissertations concerning topics within cosmic radiation. His initial academic area was cosmic radiation, but in 1962 he started researching X-ray phenomena brought forth by electron bombardment of the upper atmospherein the zone of the polar aurora. He became internationally known for his balloon experiments at the Physics Institute at the University of Bergen, and initiated a cooperation with the Max Planck Institute of West Germany in the early 1960s. He retired as professor in 1995. Trefall died 82 years old in March 2008.
Political career
Trefall started his political career in the 1983 local elections when he was elected as a city councillor for the Progress Party in Bergen. He left the party in 1986 because he thought that it no longer followed its own political program, and claimed that he finished his term by only representing the party's program, rather than its party group. He believed that the party really wanted to open the borders, and that its policy thus was too liberal with regards to immigration. Trefall was one of the founders of Folkebevegelsen mot innvandring in 1987. For the 1989 parliamentary election, he headed the list of the Stop Immigration party in Hordaland. He founded the Fatherland Party in 1990, and was elected as a Hordaland county councillor following the 1991 local elections. In 1993, he was part of a common Scandinavian meeting of immigration opponents in Oslo, where notably Denmark's Mogens Glistrup was harassed and beaten up by youth from the Blitz movement and SOS Rasisme.
Political views
Trefall's main political concern was the recent immigration to Norway. He saw the new ethnic groups as a threat to the homogenous Norwegian society, and believed that it would be devastating for the country in the long term. His solution for helping those in need, was to support them in local refugee camps, rather than letting them come to Norway. While he confirmed the equality of all humans, he believed that each country's citizens should be given special rights in relations to migrants. He was also opposed to the-then European Economic Community, which he believed would eventually crumble like the Soviet Union. He thought that the principle of open borders would destroy the common fellowship between the countries. In 2001 he argued that the call by Lars Sponheim for increased work-based immigration to Norway was akin to the "slave-owner ideology" of former societies such as the import of slaves from Africa to the Southern United States. He also argued that it was racism when Thorbjørn Jagland promoted immigration in order for the immigrants to take the "dirty jobs" Norwegians don't want. He also considered that the immigrants in turn would soon become just as discerning as the Norwegians, and that it in turn would require a continuous increase of immigration.
