リヒャルト・ワーグナー
Once again many of Wagner's supporters were in despair at the provocation. Even Cosima doubted that it was wise. By this time of course Wagner was a well-known figure and the reprint brought many counter-attacks, including: Joseph Engel, "Richard Wagner, Jewishness in Music, a Defense" ("Richard Wagner, das Judentum in Musik, eine Abwehr"); E. M. Oettinger, "An Open Love-Letter to Richard Wagner" ("Offenes Billetdoux an Richard Wagner", Dresden, 1869); and A. Truhart, "Open Letter to Richard Wagner" ("Offener Brief an Richard Wagner" St. Petersburg, 1869).
