Spelled with an S, apparently. She is 90 now and living in Zurich. She was a Nazi, perhaps even an enthusiastic one, but all is forgiven. She sang perhaps a half dozen roles, and in spite of this is one of the immortals. I was surprised to see in the annals of the San Francisco Opera that she sang the Marschallin in at least three different seasons there. They weren't afraid to repeat a success. Adler brought her to San Francisco long before the Met. She was one of his great achievements.
