marian anderson was the first black aamerican to appear there. she played the role of ulrica in "a masked ball". anderson's appearance was mostly   symbolic, she was already past her prime as a singer, and she had made her succcess on the concert stage. in her first performance, she received a ten minutes ovation. the moment was considered momentous enough at the time to warrant a front page at the new york times story.
