Wilbur

Both Wilbur and Orville were lifelong bachelors. Wilbur once quipped that he "did not have time for both a wife and an airplane". The 1909 short silent film Wilbur Wright und seine Flugmaschine (which translates to Wilbur Wright and his Flying Machine) is considered to be the first use of motion picture aerial photography as filmed from a heavier-than-air aircraft. Following a brief training flight he gave to a German pilot in Berlin in June 1911, Wilbur never flew again. He gradually became occupied with business matters for the Wright Company and dealing with different lawsuits. Upon dealing with the patent lawsuits, which had put great strain on both brothers, Wilbur had written in a letter to a French friend:

When we think what we might have accomplished if we had been able to devote this time to experiments, we feel very sad, but it is always easier to deal with things than with men, and no one can direct his life entirely as he would choose.

Wilbur spent the next year before his death traveling, where he spent a full six months in Europe attending to various business and legal matters. Wilbur urged American cities to emulate the European – particularly Parisian – philosophy of apportioning generous public space near every important public building. He was also constantly back and forth between New York, Washington, and Dayton. All of the stresses were taking a toll on Wilbur physically. Orville would remark that he would "come home white".

It was decided by the family that a new and far grander house would be built, using the money that the Wrights had earned through their inventions and business. Called affectionately Hawthorn Hill, building had begun in the Dayton suburb of Oakwood, Ohio, while Wilbur was in Europe. Katharine and Orville oversaw the project in his absence. Wilbur's one known expression upon the design of the house was that he have a room and bathroom of his own. The brothers hired Schenck and Williams, an architectural firm, to design the house, along with input from both Wilbur and Orville. Wilbur did not live to see its completion in 1914.

He became ill on a business trip to Boston in April 1912. The illness is sometimes attributed to eating bad shellfish at a banquet. After returning to Dayton in early May 1912, worn down in mind and body, he fell ill again and was diagnosed with typhoid fever. He lingered on, his symptoms relapsing and remitting for many days. Wilbur died, at age 45, at the Wright family home on May 30. His father wrote about Wilbur in his diary: "A short life, full of consequences. An unfailing intellect, imperturbable temper, great self-reliance and as great modesty, seeing the right clearly, pursuing it steadfastly, he lived and died."
