Aaron Rosand

Aaron Rosand, a leading violinist who closed out an astonishingly long career with a dramatic, emotion-filled gesture, selling his beloved rare violin for some $10 million and donating $1.5 million of that to a music institute, died on July 9 in White Plains. He was 92.

His wife, Christina Khimm Rosand, said the cause was pneumonia. He lived in Scarsdale, N.Y.

Mr. Rosand made his orchestral debut with the Chicago Symphony when he was 10 and was still performing until just a few years ago. In the intervening years he was nothing if not consistent.
