PARIS — French virtuoso pianist Brigitte Engerer, known for her brilliant interpretations of French and Russian repertoire, died in Paris on Saturday at the age of 59, her agent said in a statement. Engerer “played with some of the very best”, said Concerts de Valmalete, and “brought all of her talent to what was a continual quest for musical truth”. French President Francois Hollande said in a statement he was “saddened” by the news of her death and said Engerer’s “talent… honoured France”. Engerer always “supported young musicians… while pursuing a remarkable international career”, he said. “We will all remember her great personal bravery” in “fighting the illness that took her from us.”
