Kelly retired from acting at age 26 to marry Rainier, and she began her duties as Princess of Monaco. Hitchcock hoped that she would appear in more of his films which required an "icy blonde" lead actress, but he was unable to coax her out of retirement. The Prince and Princess had three children: Princess Caroline, Prince Albert, and Princess Stéphanie. Princess Grace retained her link to America by her dual U. S. and Monégasque citizenship. Her charity work focused on young children and the arts, establishing the Princess Grace Foundation to support local artisans in 1964. Her organization for children's rights, AMADE Mondiale, gained consultive status within UNICEF and UNESCO. She died aged 52 at Monaco Hospital on September 14, 1982, from the injuries sustained in her car crash the previous day. She is listed 13th among the American Film Institute's 25 Greatest Female Stars of Classical Hollywood Cinema. Her son, Prince Albert, helped establish the Princess Grace Awards in 1984 to recognize emerging performers in film, theatre, and dance.
