In 2019, The New York Public Library for the Performing Arts presented an extensive exhibit honoring the life and work of Harold Prince. Prince served as a trustee for the library and on the National Council of the Arts of the National Endowment for the Arts. At the behest of Lotte Lenya, whom he cast in "Cabaret" (1966), Prince also served on the Board of Trustees of The Kurt Weill Foundation for Music and as a judge of their Lotte Lenya Competition.
