Vaslav Nijinsky (also Vatslav; Russian:Ва́цлав Фоми́ч Нижи́нский; Russian pronunciation: [ˈvatsləf fəˈmʲitɕ nʲɪˈʐɨnskʲɪj]; Polish:Wacław Niżyński; 12 March 1889/1890 –8 April 1950) was a Russian ballet dancer and choreographer of Polish descent, cited as the greatest male dancer of the early 20th century. He was celebrated for his virtuosity and for the depth and intensity of his characterizations. He could dance en pointe, a rare skill among male dancers at the time and was admired for his seemingly gravity-defying leaps.
