Igor Sikorski was born on May 25, 1889 in Kiev. Both parents were doctors, but the mother never practiced. She had artistic interests and was one of Leonardo da Vinci's great admirers. Books with illustrations of this Renaissance giant were lying everywhere in the apartment, so it is not surprising that twelve-year-old Igor built a model of a helicopter powered by a rubber harness. He did not yet know that he had just found his lifelong content.
