Ignaz Brüll

 Ignaz Brüll (7 November 1846 – 17 September 1907) was a Moravian born pianist and composer who lived and worked in Vienna.

His operatic compositions included Das Goldene Kreuz (The Golden Cross), which became a repertory work for several decades after its first production in 1875, but eventually fell into neglect after being banned by the Nazis because of Brüll's Jewish origins. He also wrote a small corpus of finely crafted works for the concert hall and recitals. Brüll's compositional style was lively but unabashedly conservative, in the vein of Mendelssohn and Schumann.

Brüll was also highly regarded as a sensitive concert pianist. Johannes Brahms regularly wanted Brüll to be his partner in private performances of four-hand piano duet arrangements of his latest works. Indeed, Brüll was a prominent member of Brahms's circle of musical and literary friends, many of whom he and his wife frequently entertained.

In recent years, Brüll's concert music has been revived on CD, and well received recordings are available of his piano concertos, among other non-vocal works.

In 1872 he was appointed professor at the Horak Institute in Vienna.
