Sigurður Björnsson (1917–2008) was born at Kvísker, the son on farmer Björn Pálsson (from Svínafell) and his wife Þrúður Aradóttir. He received primary education from visting teachers during the years 1929-1931 and was a farmer at Kvísker in addition to working general work, such as bulldozer operator from the year 1951. He became a productive scholar and published articles in various magazines. His first article is probably the one on the timing of migrating birds coming to and leaving Öræfi. The article appeared in the Icelandic journal Náttúrufræðingurinn in 1935: ,,Komudagar og fardagar.” Náttúrufræðingurinn, 5. árg., bls. 182, 1935. After this he did not publish anything until after 1950. However, after 1960 he advanced as a productive writer, continuing his work until his death at the age of 91. The value of his writings is that he had knowledge of or perhaps posessed the heritage from ancient living in the Öræfi community and passed this spirit on to his and younger generations. He gathered knowledge on various matters, including natural sciences, knowledge that was about to vanish and thus he secured important history of his community. When he spoke of medieval events the story was as vidid as if it had taken place yesterday. A list of his publications is available at the Ministry for the environment and natural resources´ website, here.
