Ingrid Haebler (born Vienna, Austria, June 20, 1929). Austrian pianist. Studied at the Salzburg Mozarteum, Vienna Music Academy, Geneva Conservatory and privately in Paris with Marguerite Long. She toured worldwide, but is best known for a series of recordings from the 1950s to 1980s. Her complete recording of Mozart's piano sonatas for the Denon label are still regarded as among the finest sets, and were the source for the pirated cycle attributed falsely to Joyce Hatto.
