Biographical / Historical

Sister Gregory Duffy (? – 1995) was a long-time theatre professor at Rosary College, now Dominican University. One of her gretest achievements was her work with playwrights, including Oscar Hammerstein and Richard Rodgers. Her most notable work was on the musical “The Sound of Music,” in which she offered insight into the world of religious sisters and the mind of a postulant, as Maria was.

Sister Gregory worked in the theatre program at Rosary for thirty eight years, and also traveled extensively to grow her knowledge and understanding of theatre. Her correspondence with notables such as the above-mentioned composers, as well as with friends Florence Henderson, Mary Martin, and Richard Henderson compromises the bulk of the collection. Her relationship with those persons can be traced by reading the letters, and the advice she offered identified.

One folder of photocopied letters from the Library of Congress - Music Division was sent to the Archives by Cait Miller in April, 2012. These letters can be found filed at the end of the collection, and includes a list of individual items within the folder.

From the note accompanying the letters:

"The Hammerstein Collection contains 13 letters from Sr. Gregory. Most were addressed to Mary Martin and her late husband Richard Halliday and later forwarded to Hammerstein; however, several later letters were addressed directly to Hammerstein. The correspondence also includes 3 pages of notes from a telephone conversation Halliday had with Sr. Gregory (see item 4)."
