Margarete Wallmann

Shawn invited Wallmann to teach at his Denishawn School of Dancing and Related Arts in Los Angeles.

While Burghauser, on 12 September 1938, fled via Hungary, Yugoslavia and Italy to Canada and finally to the United States,[3] Wallmann found employment as ballet director at the Teatro Colón in Buenos Aires and became a leading figure of dance in Argentine.

Wallmann became the choice to direct premiere performances, from Darius Milhaud's David to La Scala's 1958 rendition of Turandot, with Birgit Nilsson.

In the 1950s Wallmann worked closely with Poulenc during the composition process and in evolving the structure for Dialogues des Carmélites, with the composer "becoming like an elder brother to me".

[4] In 1957 Wallmann returned to the Vienna State Opera to stage Tosca (conducted by Herbert von Karajan, and starring Renata Tebaldi), followed in later years by new productions of Dialogues des Carmelites (1959; conducted by Heinrich Hollreiser; starring Irmgard Seefried, Ivo Žídek, Elisabeth Höngen, Hilde Zadek, Christel Goltz, Rosette Anday, Anneliese Rothenberger), Assassinio nella cattedrale (1960, reviving Wallmann's 1958 La Scala production; conducted by Herbert von Karajan, starring Hans Hotter, Kurt Equiluz, Anton Dermota, Gerhard Stolze, Paul Schöffler, Walter Berry, Hilde Zadek, Christa Ludwig), La forza del destino (1960; conducted by Dimitri Mitropoulos; starring Antonietta Stella, Giuseppe di Stefano, Ettore Bastianini, Giulietta Simionato), Turandot (1961; conducted by Francesco Molinari-Pradelli, starring Birgit Nilsson, Giuseppe di Stefano, Leontyne Price), and Don Carlos (1962; conducted by Oliviero de Fabritiis, starring Flaviano Labò, Boris Christoff, Hans Hotter, Sena Jurinac, Eberhard Wächter, Giulietta Simionato).
