XU

Anne-Sofie Østvedt (later married Strømnæs) (2 January 1920 – 16 November 2009) was one of the leaders of the Norwegian intelligence organisation XU.
She started her resistance work by publishing underground newspapers, and in December 1941 XU recruited her. The Gestapo began hunting her in the autumn of 1942, and she had to live undercover for the rest of the war.
Despite her young age, she was vital to the organisation and was second in command, but her identity was a strict secret and almost none within the XU knew her. Since one of her cover names was "Aslak" - a male name in Norway - it was a huge surprise for many to meet her after the war was over.
After the end of the war she received a scholarship and from the summer of 1945 she studied chemistry at the University of California, Berkeley, graduated with a master's degree and then returned to Norway in 1951. Studying with her in California was the leader of XU, Øistein Strømnæs, whom she married.

Johan Vilhelm Aubert (7 June 1922 – 19 July 1988) was an influential Norwegian sociologist. He was a professor at the Faculty of Law, University of Oslo from 1963 to 1971 and at the Department of Sociology from 1971 to 1988. He co-founded the Norwegian Institute for Social Research already in 1950, and has been labelled the "father of Norwegian sociology". In his early life he was a member of the anti-Nazi resistance group XU, and while later involved on the radical wing of the Labour Party, he edited the newspaper Orientering.

Eilif Dahl (7 December 1916 – 17 March 1993) was a Norwegian botanist and politician for the Labour Party.
He was born in Kristiania. His interest in lichens started with an early friendship he developed with Professor Bernt Lynge. Thanks to Lynge, Dahl was able to take part in the 1936 Heimland botanical expedition to eastern Svalbard and Kong Karls Land, and then a Danish-Norwegian expedition to Greenland the next year. His collections from these excursions were used as part of his cand. real. thesis that he presented to the University of Oslo in 1942. According to Hildur Krog, his most important lichenological contribution was his 1950 work Studies in the Macrolichen Flora of SW Greenland, which was a revised version of his thesis.Dahl was appointed professor of botany at the Norwegian College of Agriculture from 1965. His research interests centered on Arctic plants and lichen, plant geography and ecology. He was also a politician for the Labour Party, where he was a board member from 1965 to 1977. During the German occupation of Norway he took part in resistance work, and was a member of the clandestine intelligence organization XU. After fleeing to neutral Sweden and later to the United Kingdom, he served with the Norwegian High Command in London.The lichen genus Eilifdahlia, and its type species, Eilifdahlia dahlii, are both named in his honour.
