Igor

Russian form of Yngvarr (see INGVAR). The Varangians brought it to Russia in the 10th century. It was borne by two Grand Princes of Kiev. Famous bearers include Igor Stravinsky (1882-1971), a Russian composer whose most famous work is 'The Rite of Spring', and Igor Sikorsky (1889-1972), the Russian-American designer of the first successful helicopter.
