WRIGHT, ORVILLE
<b>254. ORVILLE WRIGHT</b> (1871 - 1948) American inventor and a pioneer of flight, Wright, with his brother Wilbur, made the first successful flight of a motor-driven airplane. Superb aviation content, very rare T.L.S. "<i>Orville Wright</i>" on Wright Brothers letterhead, 3pp. 4to., Dayton, Dec. 9, 1912, to Henry Woodhouse in response to a galley proof of Woodhouse's article entitled "<i>The Conquest of Air</i>" for Colliers, sent to Wright for comments. In part: <i>"...Your letter enclosing galley proof of your article on `The Conquest of Air'...has been received. I have delayed answering until I had the opportunity of again looking over the work of several of the men mentioned in the paper to make sure that my recollection of their work was right. Your article is very good indeed...this criticism is mostly a matter of opinion. Sir George Cayley was a remarkable man. He knew more of the principles of aeronautics than any of his predecessors and as much as any that followed him...It is a question in my mind whether one should say that he is the originator of the monoplane, since every machine proposed prior to his time was really a monoplane...Wenham was the inventor of superposed surfaces, but...he never built a biplane. His machines possessed a number of surfaces, superposed one above the other much like the slats of a window blind. Stringfellow reduced the number of planes to three. Hargrave, Lilienthal and Chanute, I believe, were among the first to use only two. I do not think that in light of the twentieth century knowledge the `Aerial Steam Carriage' of Henson could be considered scientific for an instant. The machine was never built...Nothing in Henson's or Stringfellow's machine indicates that they had any comprehension of the principles of stability and their machines certainly indicate that they possessed no scientific knowledge in regard to the shapes of surfaces or the power required for flight...The stories of the experiments of Jean Marie le Bris are too absurd to be given serious consideration...The French inventor, Alphonse Penaud deserves a great deal of credit. Although his experiments were confined to small models, yet he was the originator of a system of fore and aft stability that is used more or less in nearly every aeroplane of the present day...I hardly think it should be said that `those early experiments (of Mouillard) laid the foundations of modern aviation'. Mouillard was an enthusiastic observer of the flight of birds, but I do not think there was anything in his work that contributed scientifically to the solution of the problem...I think the work of Maxim and Langley deserves more extended notice...</i>". Interestingly, Wright has crossed out his brother's name in type on the letter head, due to the latter's death earlier that year. Boldly signed, very good.<b> $3,500-4,500</b>
