Isabelle Dufour of Switzerland replaced Inge in 1975, and was in turn replaced by Hanna Newport, also of Switzerland, in April 1980 when she returned to nursing. In the spring of 1982, Our Chalet replaced the stone roof with a new insulated one to cut down how much heat escaped and prevent huge icicles from forming. In August 1983, five of the sixteen girls from the 1933 "Juliette Low Memorial Fund" group returned for their 50th anniversary and placed a plaque on the tree they had planted outside the library window. Newport left early in 1987 and Gwen Smith of the United Kingdom filled in until December 1987, when Maha Salhani of Lebanon took over.
