Dr. Kaare K. Nygaard was Percy Grainger's physician during the last 10 years or so of Percy's life in White Plains, NY (the early 1950s until Percy's death on Feb 20, 1961). Dr. Nygaard was in a unique position to observe Percy's illnesses and his character, and gives his fascinating insights into Percy's complex personality, motivations, and life story in this lecture at the University of Melbourne in Australia in 1985.
