Fonteyn danced until 1979, when she was nearly 60. This is unusual for any dancer, male or female. Her career was expected to end round about 1960, but it was reborn by a new partnership with a Russian dancer who had escaped from the Soviet Union. He was Rudolph Nureyev, one of the three greatest male ballet dancers of the twentieth century. Though he was 19 years younger than her, the partnership flourished, and was called "the most famous partnership in ballet history".
