Hans von Rokitansky

After retiring from the stage in 1893, he became a much celebrated singing teacher at the Vienna Conservatory and many of his pupils went on to have highly successful opera careers.

[1] Rokitansky studied music in Paris, Bologna, and Milan before making his professional singing début in an 1856 concert in London.

His many roles at that house included Giorgio in Bellini's I puritani, Leporello in Mozart's Don Giovanni, Sarastro in Mozart's The Magic Flute, Bertram in Meyerbeer's Robert le diable, the title role in Verdi's Fiesco, Caspar in Weber's Der Freischütz, the Landgrave in Wagner's Tannhäuser, and King Henry in Wagner's Lohengrin among others.

He also notably portrayed both the High priest and the Guardian of the temple in the world premiere of Karl Goldmark's Die Königin von Saba in 1875.

He appeared in operas at Her Majesty's Theatre in London in 1865 and in 1866, notably singing Osmin in a revival of Mozart's Die Entführung aus dem Serail.
