Hans Guido von Bülow (8 January 1830 – 12 February 1894) was a German conductor, pianist, and composer.
Bülow had two wives: his first wife was Cosima Liszt, daughter of composer Franz Liszt, who famously left him for Richard Wagner. After divorcing Cosima, he married actress Marie Schanzer in 1882, who later edited and published his letters.
By 1890, Bulow's mental and physical health began to fail, and he sought a warmer, drier climate for recovery; he died in a hotel in Cairo, Egypt, at the age of 64, ten months after his final concert performance.
