Karl Erb (13 July 1877 – 13 July 1958) was a German tenor. Born in Ravensburg, he was engaged at the Stuttgart opera house at the age of 30. His performance in Pfitzner’s “Der arme Heinrich” led to his bigger career at the Munich Hofoper. Rarely appearing outside of Germany, his repertoire ranged from Mozart to Donizetti, Verdi and Wagner. Quite difficult to categorize. Marriage to soprano Maria Ivogun made them the darling opera couple of the era. His Evangelist in Bach’s Passions is well received to this day.
