Ivan Rebroff (31 July 1931 – 27 February 2008) was a German-born Greek vocalist, allegedly of Russian ancestry, who rose to prominence for his distinct and extensive vocal range of four and a half octaves, ranging from the soprano to bass registers.
Rebroff was born in Berlin as Hans-Rolf Rippert to German parents of mixed Russian-Jewish descent. He studied singing at the Hochschule für Musik und Theater Hamburg. Although his knowledge and pronunciation of Russian was imperfect, he became famous for singing Russian folk songs, but also performed opera, light classics and folk songs from many other countries. He was known on stage for his gusto. He performed over 6,000 concerts in his career, including a two-year seven-day-a-week stint at the French opera, singing and acting, among other greats, the role of Tevye in Fiddler on the Roof. Rebroff still performed 12 shows in 14 days when he was well into his seventies, such as on an Australian tour.
