Included in that history is the well-known connection between Rodgers & Hammerstein's famous musical The Sound of Music and Sr. Gregory Duffy, the Dominican Sister and late theater professor, who taught at Rosary starting in 1942. Every summer, Sr. Gregory would travel to New York to go to the theatre and, in doing so, developed personal relationships with several famous actors & actresses, including Mary Martin whom she connected with after seeing South Pacific in 1949. Ten years later, when famous composers Rodgers and Hammerstein teamed up with Mary Martin and her husband, producer Richard Halliday, for a new project about the Trapp Family Singers, Sr. Gregory was contacted to provide an inside perspective on religious life for the musical's convent scenes. She began corresponding with Martin and Halliday who forwarded her letters to Hammerstein. She helped critique the script where reflections of Catholic traditions and interactions of the religious could be made more authentic and in late 1959, she communicated directly with Hammerstein and offered him spiritual guidance as he faced stomach cancer.
