I met her at Swarthmore College in 1978, at a complete performance of the piece one of my piano teachers always called “Give My Regards to Jesus”. (Why Swarthmore, you ask? Gerald Levinson, composer on the Swarthmore faculty, was one of Messiaen’s few American pupils.) Of the pianists I have heard do the piece, only Peter Serkin and Pierre-Laurent Aimard could get the variety of color that she achieved.
Did you know she premiered the Boulex 2nd Sonata? Or played a cycle of 22 Mozart concerti? Or ran the tape recorder on joint ornithological expeditions with her husband?
