Octave Chanute

Died 23 Nov 1910 at age 78 (born 18 Feb 1832). American aeronautical engineer whose work and interests profoundly influenced Orville Wright and Wilbur Wright and the invention of the airplane. Chanute was a successful engineer who took up the invention of the airplane as a hobby following his early retirement. Knowing how railroad bridges were strengthened, he experimented with box kites using the same basic strengthening method, which he then incorporated into wing design of gliders. Through thousands of letters, he drew geographically isolated pioneers into an informal international community. He organized sessions of aeronautical papers for the professional engineering societies that he led; attracted fresh talent and new ideas into the field through his lectures; and produced important publications.
