Of Greek and Italian descent, Dalis grew up in
San Jose, California. Dalis received her bachelor's degree from San Jose State College (now
San José State University) and master's degree in music education from
Teachers College of Columbia University, and she received honorary doctorates from
Santa Clara University and San Jose State University. Dalis was awarded a
Fulbright scholarship and went to Europe to begin her singing career. She studied in
Milan and gave her first performance of any kind at the Oldenburgisches Stadttheater in Germany. This was so successful that she was offered a contract in
Oldenburg and remained there for two years between 1953 and 1955, making her professional debut there in 1953 as Princess Eboli in Verdi's
Don Carlo. She then moved to the Berlin's
Städtische Oper where her performance in Janáček's
Jenufa led to an offer from
The Metropolitan Opera, where she debuted in 1957, again as Eboli, to great applause. One New York City reviewer, Raymond Erickson, wrote: Her expert vocalism and musicianship were immediately apparent in the "Veil Song", which Dalis sang better than I have ever heard it sung. In the tricky ensemble with Carlo and Rodrigo in the Queen's gardens, she was just as impressive, and her sweeping, almost torrential handling of
O don fatale won her a genuine ovation from the capacity audience. Everywhere, Dalis' acting went hand-in-glove with her singing. Erickson concluded that Dalis's debut was "one of the most exciting in recent seasons" That was the first of 274 performances with the Met, over 20 seasons. She was particularly noted as Amneris in Verdi's
Aïda, a part she sang 69 times at the Metropolitan. She was Brangäne when
Birgit Nilsson sang first at the Met in Wagner's
Tristan und Isolde in 1959, Amneris when
Leontyne Price debuted in
Aïda at the house in 1961 and Princess di Bouillon for
Plácido Domingo's Met debut in
Adriana Lecouvreur. She also performed with soprano
Leonie Rysanek frequently, most notably 17 performances of
Die Frau ohne Schatten by Richard Strauss, as well as in
Salome and
Aida. ==Career highlights==
