Jacques Rouché invited 24-year-old dancer Serge Lifar to become the maitre de ballet of the Paris Opéra Ballet, which had fallen into decline in the late 19th century. As ballet master from 1930 to 1944, and from 1947 to 1958, he devoted himself to the restoration of the technical level of the Opéra Ballet, returning it to its place as one of the best companies in the world. Lifar gave the company a new strength and purpose, initiating the rebirth of ballet in France, and began to create the first of many ballets for that company. During his three decades as director of the Paris Opéra Ballet, Lifar led the company through the turbulent times of World War II and the German occupation of France. Lifar brought the Paris Opéra Ballet to America and performed to full houses at the New York City Center. Audiences were enthusiastic and had great admiration for the company of dancers. Era of Rudolf Nureyev In the world of ballet, Rudolf Nureyev is regarded as the greatest classical dancer ever and as one of the most preeminent choreographers. In 1983, Rudolf Nureyev was appointed director of the Paris Opera Ballet, where, as well as directing, he continued to dance and to promote younger dancers. The top female ballet dancer at that time, if not of all times, was Sylvie Guillem, who was nominated principal dancer at the age of 19 by Rudolf Nureyev in 1984. They were an exceptional dance couple. The years of Nureyev marked a golden era of the Paris Opera Ballet. Brigitte Lefèvre Brigitte Lefèvre, director from 1995 to 2014, with Patrice Bart as maitre de ballet from 1990 to 2011, succeeded to maintain the high standard that Nureyev has set. Brigitte Lefèvre invited some of the most preeminent choreographers, such as William Forsythe, Angelin Preljocaj, Saburo Teshigawara, and John Neumeier. Transition There were turbulent times for the company with Benjamin Millepied, director of the Paris Opera Ballet from November 2014 until he quit on 15 July 2016. There were two stumbling blocks with Millepied, a French dancer and choreographer, who left France in 1993, at the age of 16, got his main professional education as a dancer and choreographer in the United States and came back to France in 2014 as newly appointed director of the Paris Opera Ballet. The first one was that Millepied wanted the Paris Opera Ballet dancers
