Cosima was a child of the passionate and stormy union between Franz Liszt and Marie d'Agoult. She married her father's brilliant pupil Hans von Bulow, but her husband's devotion to the "master" he idolized, Richard Wagner, led Cosima to a great passion for Wagner. Scandel and divorce followed, but it was as Cosima Wagner that her life found fulfilment. She gave Wagner the total devotion that he needed, making possible the completion of the Ring cycle of operas and the realization of his dream that became Bayreuth.
The author was a student of Alexander Siloti who was a pupil of Liszt.
