(b Wellington, 31 Dec 1931; d Auckland, 4 March 1995). New Zealand bass. After training initially as a tenor, he made his début as a bass-baritone in Auckland in 1957 as Giorgio Germont. Three years later he made his Australian début as Sarastro, by which time his voice had developed a true bass depth and resonance. After further study in Paris with Dominique Modesti (1961–2), he sang with Sadler's Wells Opera (1963–7) and at the Hamburg Staatsoper from 1967 until he began a freelance career in 1977. In Hamburg he sang Black Will in the première of Alexander Goehr's Arden Must Die in 1967. From 1979 he regularly sang Fafner, Hunding and Hagen in Seattle Opera's annual bilingual Ring productions, and from 1977 he made frequent appearances with Victoria State Opera. Mangin claimed to have 189 roles in his repertory, of which the most notable were Don Pasquale, Ochs and, especially, Osmin, which he recorded twice. He was made a Kammersänger at Hamburg in 1976 and created an OBE in 1981.
