I don't know, but he sounds suspiciously like the famous composer Igor Stravinsky - just substitute a couple of initial capitals, and swap two letters round in the surname, and there you have him. Stravinsky was a Russian-American composer, noted particularly for his Ballet scores, who lived from 1882 to 1971.
That is Igor Sikorski, and he was in his 40 's when he invented the first practical helicopter.
