The role of Baron Ochs in the world premiere was passed to German bass Karl Perron (1858-1928) after the services of Richard Mayr could not be acquired. Although he may not have been Strauss's first choice, Perron was evidently regarded highly enough by him to have been chosen to create Jochanaan in his Salome and Orestes in his Elektra. However, in correspondence between the composer and librettist, there are indications that Strauss was considering the services of Paul Bender just in case Perron did not work out in the role of Ochs: "In case you and Reinhardt [the producer] do not succeed in grooming Perron for the part, I give you full powers of veto to cancel the premiere with Perron on the 26th. . . . [Perron] is such a first-class artist that he will understand and share our misgivings."German lyric tenor Robert Philipp (1852-1933) as Don José in Carmen. He began a career as an actor in Berlin. In the 1880s he took up singing in operettas in that same city. In 1890 he made his first appearance in grand opera at the Berlin Imperial Opera where he remained the rest of his career. He was married to soprano Marie Dietrich.
