Born May 22, 1916, in Missoula, Montana, the 86-year-old Amundsen was the wife of longtime missionary Hans Roald Amundsen, who served the Evangelical Covenant Church (ECC) in Alaska for many years after being called by the Department of World Mission in 1945. After many years in Nome, the family moved to Soldotna in 1964 and began Missionary Aviation and Repair Center, a key transportation ministry for Alaska.

While her husband ran most of the operations for Missionary Aviation, Harriett worked as a secretary for two local schools. Harriett had graduated from Seattle Pacific University with a teaching degree before she and her husband began ministry in Alaska.

Harriett is survived by her husband of 58 years, Hans Roald Amundsen; daughter and son-in-law, Jeanette and Gary Klodt; son and daughter-in-law, John and Susan Amundsen; son Tim Amundsen; and grandchildren Amber and Hans (and wife Misty) and great-granddaughter, Krysta, all of Alaska. She is also survived by sister Eleanore Bloom of Turlock, California.
