In 1977, the 90-year-old Rubinstein left his wife Nela Młynarska after 45 years of marriage for Whitestone[5] and lived with her in Geneva, Switzerland,[6] until he died in 1982. Whitestone helped Rubinstein to write the second volume of his autobiography, My Many Years, which he dedicated to her. Rubinstein's first collaborator was Tony Madigan, whom he met in Marbella,[7] and he transcribed the early part of the book.[8]
Annabelle Whitestone was married to British publisher Lord Weidenfeld from 1992 until he died in 2016.[11] She later began a relationship with pianist Menahem Pressler, whom she had known since 1966, and lasted until his death in 2023.[12]

"Annabelle Whitestone had been educated in a convent and had had musical training. She had first heard Rubinstein play—Beethoven's Fourth Piano concerto with Barbirolli—in London in 1961, when he was awarded the gold medal of the Royal Philharmonic Society. Her career in concert management had begun with the firm of Ingpen & Williams, and she had also worked for Ibbs & Tillett before she joined Van Wyck's forces. Not many weeks after her first encounter with Rubinstein, she left Van Wyck, at the suggestion of Henryk Szeryng—one of the artists whom she had managed—and went to Madrid to work for Ernesto de Quesada's son Ricardo, who was gradually taking over the direction of the Spanish branch of the Daniel agency. "The Quesadas, who had befriended Annabelle and who were eager to please their most celebrated client, assigned her to look after him on his Spanish trips and allowed her to disappear at a moment's notice when he summoned her: she would fly to Paris or elsewhere, whenever he was alone and free for a day or two. "I had a full time job in Madrid, and a very serious one," she said. "We dealt with all the biggest artists—Arrau, Menuhin, everybody—and they were very much my responsibility; they would arrive, and I would suddenly say to Ricardo, 'Look, I'm going to Paris the day after tomorrow.' He never made any objection. I don't know what I would have done without the Quesadas as friends." According to Annabelle, the only person besides the Quesadas who knew what was going on was Louis Bender, the trusty Hurok employee who looked after Rubinstein on his American tours."
^From Publishers Weekly "In the last decade of his life, he began a liaison with a young English concert promoter, Annabelle Whitestone (now married to British publisher Sir George Weidenfeld)."
