The Romanian coloratura soprano, Yolanda Márculescu [Iolanda Mărculescu; Yolanda Marcoulescou, Yolanda Marculescu-Stern] was born in Bucharest to a family of Wallachian boyars. She studied at the Conservatory of Bucharest under the direction of the tenor Constantin Stroescu. When she was 20 years old, she joined the Romanian State Radio Chorus Ensemble. At the end of World War II, she joined the Romanian National Opera in Bucharest and by 1948 was the leading soprano.
Yolanda Márculescu married Sandu Stern, who was the first violinist of the Bucharest Symphony Orchestra and of Jewish heritage. She was the prima donna of the Bucharest Opera for 20 years, appearing in more than 1,500 performances. She starred extensively throughout Europe and the Far East in engagements in Austria, Czechoslovakia, East Germany, Finland, Hungary, Poland, the Soviet Union and Yugoslavia, as well as China and Vietnam. Some of her most noted roles were as the title role in Lakmé by Léo Delibes; Despina in Così fan tutte, Susanna in The Marriage of Figaro and Zerlina in Don Giovanni by W.A. Mozart; and Lisetta in Amorul doctor by Pascal Bentoiu. Besides Susanna, her personal favorite roles included Rosina in Rossini's The Barber of Seville; Gilda in Rigoletto and Nannetta in Falstaff, both by Verdi. Her specialty was singing Lieder. In addition to performance, she taught voice at the Bucharest Music Academy from 1962 to 1968.
Shortly after Nicolae Ceaușescu assumed control of the State Council in December 1967, becoming de jure head of state of Romania, Yolanda Márculescu and Stern began making plans to leave. It took from March to August 1968 to obtain the tourists visas from Romania, but they were unable to secure permission for Mărculescu's mother. The couple fled with her husband's mother to Austria and their defection branded them as enemies of the state. Convicted of treason, they were sentenced to twenty years in prison should they return, forcing friends and relatives to distance themselves or face persecution. Her records and television recordings were destroyed, though a few managed to survive. When they left, she had just recorded an album containing arias of Georges Bizet, Charles Gounod, W.A. Mozart and Rossini. She was surprised that it was pressed, but received copies of it from friends, though it was banned on the radio. With the assistance of the Viennese branch of the Hebrew Immigrant Aid Society, and the American Jewish Joint Distribution Committee they relocated to the USA, in October 1968, first settling in Chicago, where Marculescu taught at Roosevelt University.
In 1969, Sandu was hired by the Milwaukee Symphony Orchestra and the couple moved to Wisconsin. Yolanda Márculescu found a teaching position that same year at the University of WisconsinMilwaukee. She began as an associate professor and taught French and German repertoire. She also directed the Opera Theater of the School of Fine Arts. In 1974, the couple became naturalized American citizens and in 1975, she recorded an album for Orion Records featuring songs by the Romanian composer George Enescu and French composer Albert Rousse. In 1981, she founded the International Festival of the Art Song, which was held biennially until her death in Milwaukee. The festival was designed to teach art song to students and the public by bringing European artists to perform and conduct master-classes.
In 1991, after the fall of communism, Yolanda Márculescu was invited to return to Romania as a juror for the George Enescu Festival. She returned to the United States and that same year received the Distinguished Teaching Award from the University of WisconsinMilwaukee. In 1992 she was honored by the Milwaukee Civic Music Association Award and then retired from her professorship in June, 1992. She died on December 19, 1992 in Milwaukee, Wisconsin after a year long battle with cancer. Posthumously, a scholarship bearing her name was instituted at the National University of Music Bucharest by a former student, Georgeta Stoleriu. In 2013, a book about her life, written by Ileana Ursu was released by Editura Muzicală.
