The Wright brothers received their copy of Chanute’s book personally from the author, who became both their friend and advisor. At their invitation, Chanute visited the Wrights at Dayton, Ohio and Kitty Hawk, North Carolina. It was Octave Chanute who, at a meeting in December, 1903, of the American Association for the Advancement of Science announced to the world that the Wright Brothers had flown in a heavier than air machine.
