Lehmann coached, taught, directed and “master-classed” a huge number of singers. She was always proud of her students and their accomplishments. In every interview she managed to include some of their names.
Some articles and books have mentioned fine singers as Lehmann students, who did NOT study with Lehmann. The following: Shirley Verrett, Mattiwilda Dobbs, and Elisabeth Schwarzkopf never studied with Lehmann.
