Because of the importance of this suit in aviation history, it is worth while to examine the background of the relations between the Wrights and Glenn Curtiss. The Wrights’ personal acquaintance with Curtiss began in May, 1906, when he wrote to them in regard to the light motors of which he was a manufacturer. Then in early September, 1906, Curtiss visited the Wright office and workshop. He was brought there by his friend, Captain Thomas S. Baldwin, a well-known aeronaut, who was giving exhibition flights in Dayton with his dirigible balloon on which he used a motor he had persuaded Curtiss to build for him. It was to make repairs on that motor that Curtiss had come to Dayton.

After that meeting, the four men, Curtiss, Baldwin, and the Wrights, were together much of the time for several days. When in response to questions about their work, the Wrights showed a number of photographs of their flights made at the Huffman pasture during the two previous years, Curtiss seemed much astonished. He remarked that it was the first time he had been able to believe anyone had actually been in the air with a flying-machine.

Long afterward, in an interview in the New York Times (February 28, 1914), Baldwin recalled the many talks he and Glenn Curtiss had with the Wrights in that fall of 1906. “I sometimes suggested to Curtiss,” Baldwin told the interviewer, “that he was asking too many questions, but he kept right on. The Wrights had the frankness of schoolboys in it all and had a rare confidence in us. I am sure Curtiss at that time never thought of taking up flying.”

A year after the Wrights’ first meetings with Curtiss, in October, 1907, the Aerial Experiment Association was formed by Alexander Graham Bell and others, with headquarters first in Nova Scotia and later at Hammondsport, N. Y., where Curtiss lived. He became “Director of Experiments.” This was the first time Curtiss had been directly connected with aviation except as a manufacturer of motors, and three months later, a letter he wrote to the Wrights indicated that motors rather than aviation were still his chief interest. “I just wish to keep in touch with you,” he wrote, “and let you know that we have been making considerable progress in engine construction.” After listing and describing the various engines he was building, he proposed to furnish to the Wrights “gratis” one of his fifty-horsepower engines. But the offer was not accepted. The letter mentioned that Captain Baldwin was a “permanent fixture in this establishment”—a fact not without importance, considering information that Baldwin was later to reveal. Further on in the letter, Curtiss told of Dr. Bell’s reading to the members of the Aerial Experiment Association the United States Government’s specifications for the purchase of a flying-machine, and added: “You, of course, are the only persons who could come anywhere near doing what is required.”

About a fortnight after receipt of that letter from Curtiss, the Wrights got another letter dated January 15, 1908, written on Aerial Experiment Association stationery, and signed by Lieutenant T. Selfridge, whose name appeared on the letterhead as secretary of the association. (This was the same Selfridge who was killed a few months later in the tragic airplane accident at Fort Myer.) In that letter, Selfridge, on behalf of the Experiment Association, said:

I am taking the liberty of writing you and asking your advice on certain points connected with gliding experiments, or rather glider construction, which we started here last Monday.

Will you kindly tell me what results you obtained on the travel of the center of pressure both on aerocurves and aeroplanes?

Also, what is a good, efficient method of constructing the ribs of the surfaces so that they will be light and yet strong enough to maintain their curvature under ordinary conditions, and a good means of fastening them to the cloth and upper lateral cords of the frame?

I hope I am not imposing too much by asking you these questions.

Supposing the information would be used only for scientific purposes, the Wrights obligingly replied at once as follows:
