Dr. George Spratt--A Letter and a Lost Friend

One More Chapter on the Wrights Invented What?

"After having for twenty years capitalized upon this as your own work I do not see how you can give a correct account of this without bringing yourselves into open censure"--Dr. George Spratt to Orville Wright, 1922, on the development of the Wright flyer.

Dr. Spratt as an Inventor

The concepts behind Spratt's amazing control wing invention were beyond Wilbur Wright's understanding, as clearly revealed in his letters to the doctor. Contrary to what we are taught, it was Spratt's ideas that the Wrights used to build their wind tunnel. Link here to great youtube videos of Spratt's control wing in flight and a few derivations of his invention..

  Dr. Spratt's Relationship with the Wrights

An early friend of the Wright brothers, Dr. George Spratt wrote his last letter to Orville Wright in 1922. See it below. Was it it an expression of sour grapes or a statement of the betrayal of a once loyal friend? You be the judge. I've emphasized some of the copy, so it's obvious where I stand. As you read today's Wright "history," as it was carefully pruned and shaped by the Wrights, look for the explanations and rationalizations they write for primary documents, such as this letter. It would seem that Dr. Spratt was wrong when he said "It makes little difference what you write, history writes itself."

Dr. George Spratt was another pioneer aviator, who like Edward Huffaker, came to Kitty Hawk in 1901 at the request of  Octave Chanute. Like Huffaker and Chanute, Spratt freely provided the Wrights with suggestions and help.

Wilbur publicly admitted early on that both Spratt and Huffaker had educated him on the movement and reversal of the center of pressure as a plane changes its angle of attack. But neither Wilbur nor  Orville repeated that admission any time later.*

 In 1901 at Kitty Hawk, the Wrights had warmed to Spratt, unlike Huffaker (see previous blog post), and invited him back in 1902 and 1903. A lively correspondence sprang up between Wilbur and the doctor and information was exchanged. However, when the Wrights began their insults to early aviation by suing anyone they thought infringed on their 1906 glider patent, Spratt's response began to cool. Further, Spratt requested recognition for his important contributions to the Wrights' wind tunnel tests and later asked for help in building his "control wing" plane.Wilbur wrote back that it was enough that he had sent Spratt tables from the wind tunnel tests and shared information of his own. They were square and he owed him nothing.(What?)  It is now established that the Wrights wanted the world to believe that their research was theirs and theirs alone--a myth that came to prevail..

Eventually, the friendship with the Wright brothers soured to the point that Spratt no longer would answer their letters.

 Dr. Spratt's Stinging Last Letter to Orville Wright

Much later, in 1922, Orville Wright wrote Spratt for copies of the brothers' letters they had written to him over the years-- (he also tried to acquire Wilbur's letters to Octave Chanute that were in the possession of his daughters after his death.) Orville was apparently compiling his version of the early history of aviation.

 The following letter is Dr. Spratt's response to Orville's request in its entirety. Those who are interested in truth in aviation history need to read this letter carefully:

* I have been since informed that Orville admitted some twenty years later Spratt's and Huffaker's educating the Wrights about the movement of the center of pressure. I will have to research this.
