Read excerpts from the biography and memoir. Biography: Wilbur and Orville Wright came from a family who valued education. Their father was a minister and had plenty of books in the family library for the boys to read. When Wilbur was eleven and Orville seven, their father bought them a toy helicopter that sparked their interest in flight.

Memoir: Late in the autumn of 1878, our father came into the house one evening with some object partly concealed in his hands, and before we could see what it was, he tossed it into the air. Instead of falling to the floor, as we expected, it flew across the room till it struck the ceiling, where it fluttered awhile, and finally sank to the floor. It was a little toy, known as a “helicopter,” but which we at once dubbed a “bat.”
