When Did Hans Neuenfels Die?

Hans Neuenfels was a German writer, poet, film producer, librettist, theatre director, opera director and theatre manager. As a director, he first focused on drama, staged at prominent houses such as the Vienna Burgtheater, and became a leading exponent of German Regietheater. From 1974, he turned to opera, looking for "the subliminal of the music and the interlinear of the texts", for "surprisingly new, sometimes even disturbingly ambivalent perspectives on the works".
