He found fame performing pieces by famed German composer Richard Wagner and made his international breakthrough in a 1975 production of Wagner's Tristan and Isolde, taking on the male lead. Wenkoff subsequently hit the stage with the Berlin State Opera, the Metropolitan Opera in New York and the Vienna State Opera, among others.
