Wanda Toscanini Horowitz

When Arturo Toscanini refused to speak with her sister, Wally, following her affair with a married man, it was Wanda who confronted her father and insisted he reestablish contact.

In the 1950s, when Horowitz was playing a Schubert sonata, she complained of the work's length, which persuaded the pianist to forgo a repeat.

[2] She pointedly declined to accompany her husband for much of his 1983 tour, when he refused to accept that medications were adversely affecting his playing.

Mrs. Horowitz took a central part in arranging her husband's activities, in fact in nearly all aspects of his life.

Byron Janis, one of Horowitz's students, has written that he and Wanda were involved in a brief affair during this period.

Arthur Rubinstein stated that "Wanda was a very hard woman—hard as stone, and this was undoubtedly a factor that led to Volodya's collapse".

[3][10] Wanda was entombed alongside her husband in the Toscanini family crypt at Cimitero Monumentale in Milan.
