Opera Singer. One of his generation's noted baritones, he had a long career at Munich's Bavarian State Opera that saw him receive the now honorary title of Kammersanger. Raised in Dusseldorf he originally apprenticed as a meat-cutter in his family's shop then studied voice for several years with Berthold Puetz in Krefeld. After further training in Cologne he made his 1948 operatic bow in his home city as Morales from Bizet's "Carmen"; Imdahl was to spend the next years in Munich refining his craft in smaller roles before moving on to Bremen in the mid 1950s where he sang his first lead as the tragic title court jester of Verdi's "Rigoletto". The following seasons were to see him in the major opera houses of Zurich, Vienna, Berlin, and elsewhere, his roles including Amonasaro from Verdi's "Aida", John the Baptist in Richard Strauss' "Salome", Pizarro from Beethoven's "Fidelio", Count di Luna in Verdi's "Il Trovatore", and Baron Scarpia, the evil police chief of Puccini's "Tosca". Engaged at the Bavarian State Opera from 1959 until his 1988 retirement, Imdahl added other roles to his repertoire including the Music Teacher of Strauss' "Ariadne auf Naxos" and the villainous Iago of Verdi's "Otello" as well as most of Wagner's principal baritone parts among them Hans Sachs in "Die Meistersinger", Telramund in "Lohengrin", Kurwenal from "Tristan und Isolde", Amfortas in "Parsifal", Wolfram from "Tannhauser", and Wotan of "The Ring Cycle". Continuing to travel he made his 1965 American bow at San Francisco as Hans Sachs, was first heard at Naples' Teatro San Carlo in 1970 as John the Baptist, and had his 1972 bow at Covent Garden, London, as the Music Teacher. The owner and operator of an upscale Lake Chiemsee hotel from 1961 on he remained active into advanced years, continuing to sing in his church. Though his recorded legacy was fairly small much of it remained available at his death.
