Annabelle Whitestone, Lady Weidenfeld, is an English former concert manager and promoter for classical music impresarios including Ingpen & Williams, Ibbs and Tillett, Wilfrid Van Wyck, and Conciertos Daniel.
The famous Polish-American pianist Arthur Rubinstein credited Whitestone with assisting the careers of two of his protégés, François-René Duchâble and Janina Fialkowska, as well as introducing him to the chamber music of Mozart, Haydn, and Beethoven "with all sorts of combinations of string and wind instruments which I never even heard."
In 1977, the 90-year-old Rubinstein left his wife of 45 years for Whitestone and lived with her in Geneva, Switzerland until his death in 1982. Whitestone helped Rubinstein to write the second volume of his autobiography, My Many Years, which he dedicated to her. Rubinstein's original collaborator, Tony Madigan, whom he met in Marbella, transcribed the first phase of the book.
Whitestone convened Remembering Rubinstein, a day of talks and concerts at the Royal Academy of Music on 22 January 2008, to honor the pianist "who once sold as many records as rock stars and was as much at ease in the White House as he was with his chums Picasso and Charlie Chaplin." Lady Weidenfeld is a member of the International Advisory Board of the Jerusalem Music Centre and the Jerusalem Foundation and a member of the Honorary Advisory Board of the Jewish Music Institute SOAS.
Annabelle Whitestone has been married to British publisher George Weidenfeld since 1992.
