Gordon Tracie introduced this dance to the Scandinavian dance community and international folk
dancers during his teaching career. I had the pleasure of learning it from Gordon Tracie at one such workshop. The following information is taken from Dance a While 1978 and 1988 editions.
“This dance has been popular in the United States for at least fifty years. Gordon E. Tracie in his study of dances in Scandinavia in 1948 discovered that such a Swedish waltz was not danced in Sweden. However, an elderly couple from the country (Dalarna, Sweden) recognized it as the nearly forgotten "Norsk Vals" (Norwegian waltz), which they had danced in their youth. Scandinavian immigrants undoubtedly brought the dance to this country at the turn of the century.”
