In 1934, William E. Boeing sold his holdings and left active leadership of the aviation enterprises he had spent nearly two decades building. What began as a small Seattle airplane venture had expanded into manufacturing, engines, and commercial air transport. New federal airmail rules required that integrated business to break apart.
It was a striking turn for a businessman who had begun in timber. Family resources gave Boeing a start; engineers and pilots helped make his aircraft venture possible; military contracts kept it growing and then exposed it to a collapse in demand. Airmail opened another market. The same reliance on government contracts that helped the enterprise expand would become central to the events surrounding his departure.
A Quick Look at the Life of William E. Boeing
Biography Summary
William E. Boeing (1881–1956) was an American businessman who founded Pacific Aero Products Co. in Seattle in 1916, the predecessor of the Boeing Airplane Company. Drawing on resources developed through timber and land investments, he organized an early aircraft venture, secured military work, expanded into airmail and passenger transportation, and became chairman of United Aircraft and Transport Corporation. He stepped away from aviation leadership in 1934 and continued with property, farming, and other interests.

From Detroit to the Washington Timber Business
William Edward Boeing was born in Detroit on October 1, 1881. His parents were Wilhelm Böing, later known as William Boeing, and Marie Ortmann. His father, a German immigrant, had amassed substantial assets through timber, land, and mineral interests before dying in 1890, when William was still a child.
The family’s wealth mattered to the opportunities available to the younger Boeing. He was not beginning his career without money or commercial connections. After schooling in Vevey, Switzerland, and studies at Yale’s Sheffield Scientific School, he left college without a degree and entered the timber business in Washington state in the early 1900s.
Working around Grays Harbor and Hoquiam, Boeing developed timber and land interests, including the Greenwood Timber Company. He could draw on family holdings and contacts while building business operations of his own. In 1908 he moved to Seattle, continuing his involvement in timber as another industry was beginning to attract his attention.
From Watching Airplanes to Flying One
At a 1910 aviation meet near Los Angeles, Boeing tried to obtain a ride with aviator Louis Paulhan but was unsuccessful. His next documented steps toward flying came several years later.
In 1915, Boeing flew as a passenger with a visiting seaplane aviator, took flying instruction with Glenn L. Martin, and purchased a Martin seaplane. He was no longer merely watching airplanes; he was learning to operate one.
Boeing joined forces with George Conrad Westervelt, a U.S. Navy officer who shared his aviation interests. They pursued a new floatplane incorporating changes to the Martin design. Boeing supplied organization and financing; Westervelt brought engineering involvement, while mechanic and pilot Herb Munter and other workers contributed to construction and testing. The effort also included structural assessment and wind-tunnel work.
Westervelt’s Navy assignment took him east before the aircraft’s first flight, but the collaboration gave the new machine its name: the B&W, for Boeing and Westervelt.
The Bluebill Flies—and a Company Takes Shape
On June 15, 1916, Boeing piloted the B&W Model 1, known as the Bluebill, on its first flight from Seattle’s Lake Union. A second B&W aircraft, the Mallard, followed. Neither produced the hoped-for U.S. Navy production order; both were eventually sold to New Zealand.
The lack of an immediate Navy customer did not end the venture. On July 15, 1916, Boeing incorporated Pacific Aero Products Co. The business operated from early Seattle facilities that included a former shipyard and the plant later remembered as the Red Barn. In 1917 it became the Boeing Airplane Company.
Incorporation gave the aircraft venture a formal business structure, but the unsuccessful Navy bid left the question of large-scale orders unanswered.
The Navy Contract That Turned a Workshop Into a Manufacturer
That customer arrived during World War I. Following the United States’ entry into the conflict in 1917, the Navy ordered 50 Boeing Model C training seaplanes. The contract provided the young company with its first substantial aircraft-production success.
The Model C was also a reminder that Boeing’s business depended on specialized talent. Chinese-born aeronautical engineer Wong Tsu, who joined in 1916, played an influential role in its development. His aeronautical expertise, including work connected to wind-tunnel experimentation, complemented the contributions of other early employees such as James Foley and Herb Munter. Boeing organized and led the business; the engineering and manufacturing were collaborative achievements.
With military work growing, Boeing also paid attention to the federal government as a customer. In 1917 he established a business presence in Washington, D.C., to keep in touch with government activity and prospective contracts. In company correspondence, he argued for having someone “on the ground [in Washington, D.C.] at all times.”
The order gave the young company the work needed to expand production. Its dependence on military customers, however, would soon become a serious vulnerability.
When Wartime Orders Disappeared
The armistice in November 1918 brought a severe contraction in aircraft orders. Contracts were reduced or canceled, and the Boeing company cut its workforce dramatically. An enterprise that had expanded to build military airplanes now had more production capacity than the market required.
Instead of relying solely on new aircraft sales, the factory used its woodworking capabilities to make furniture and other products, including boats. Boeing also drew on his financial resources and other business activity to help keep the operation going. These non-aircraft jobs were practical work for an underused plant, not evidence that its founder had abandoned aviation.
Early-1920s military contracts, including work on Thomas-Morse MB-3 fighters, contributed to recovery. The assignment also showed another side of the manufacturer’s role: it could build aircraft designed by others rather than only models developed in its own shop.
Military work had helped the factory recover. The development of contracted airmail would eventually give Boeing another commercial opportunity.
From an Experimental Mail Flight to a Scheduled Airline
On March 3, 1919, Boeing and pilot Edward “Eddie” Hubbard flew a modified Model C to Vancouver, British Columbia, and brought 60 letters back toward Seattle. The pioneering cross-border airmail trip came with difficulties, including a low-fuel landing short of Seattle. Scheduled service would take several more years to develop.
Hubbard later advocated entering the business of contracted mail carriage. Once federal rules permitted private operators to carry mail under contract, Boeing’s enterprise competed for a route between San Francisco and Chicago and won it.
Boeing Air Transport began operations on July 1, 1927. Its Boeing Model 40A aircraft could accommodate both mail and passengers, connecting a government-supported transport service with the growing possibility of passenger flying. Mail payments helped sustain the operation of commercial routes at a stage when passenger demand alone was not the entire business.
Unlike the single mail flight of 1919, Boeing Air Transport operated a contracted route. Boeing now had interests in manufacturing aircraft and using them in commercial service. The broader business also opened the Boeing School of Aeronautics in Oakland in 1929.
Building an Aviation Group Beyond the Airplane Factory
By the end of the 1920s, aircraft production, engines, and airlines were becoming more closely linked through mergers and corporate arrangements. In 1929, Boeing’s manufacturing and transport interests combined with other aviation businesses, including Pratt & Whitney, to create United Aircraft and Transport Corporation. Boeing became its chairman.
The resulting enterprise brought together aircraft and engine manufacturing with commercial air transportation. It was a major expansion of the business interests that had begun with a small Seattle aircraft venture, and it connected Boeing to a national industry in which government airmail contracts remained an important source of revenue.
That connection to federal contracting would also place the combined businesses under intense public scrutiny. The rules and practices that helped shape the industry in the 1920s would not remain unchanged.
The Airmail Investigation and the 1934 Breakup
Beginning in 1933, a special U.S. Senate committee chaired by Hugo Black investigated air- and ocean-mail contracts. The inquiry examined the award of mail contracts and the relationships among postal officials and airline executives. The Senate’s historical account describes noncompetitive awards and conflicts of interest involving government postal officials.
The committee’s investigation exposed problems in the federal mail-contract system. It was not a criminal conviction of William Boeing. The findings about noncompetitive awards and government conflicts of interest concerned contracting practices rather than a court judgment against the founder.
In 1934 the Roosevelt administration canceled existing airmail contracts and briefly assigned mail flying to the Army Air Corps. Fatal flying accidents followed. Mail service subsequently returned to private carriers, but the contracting framework had changed.
New rules barred the same corporate organization from combining aircraft manufacturing with ownership of an airmail carrier. United Aircraft and Transport was broken into separate successor businesses, including Boeing Airplane Company, United Air Lines, and United Aircraft. The combined empire that Boeing had chaired could not continue in its previous form.
Amid the investigation and restructuring, Boeing sold his holdings and withdrew from active aviation-company leadership in 1934. The successor businesses continued separately, without him at the head of the integrated group.
Other Businesses, Family Life, and a Different Kind of Legacy
After leaving aviation leadership, Boeing continued to pursue investments and activities outside aircraft manufacturing. Timber interests remained part of his business life. He also worked in real-estate development around Seattle and later pursued farming, livestock, and horse breeding, including activities associated with Aldarra Farm near Fall City. During World War II he provided consulting assistance, but he did not return to running the aircraft manufacturer’s wartime programs.
Boeing married Bertha Potter Paschall in 1921. She had two sons from an earlier marriage, and together they had a son, William E. Boeing, Jr. The family lived for many years in a house Boeing commissioned in Seattle’s Highlands community, designed by Charles Bebb. He later gave the house to Children’s Orthopedic Hospital, an institution he supported.
His land-development record includes a more troubling and consequential fact. Residential property developed on land held by William and Bertha Boeing, including the Blue Ridge area, carried racially restrictive covenants that excluded residents on the basis of race. Recorded protective restrictions from 1938 identify the Boeings’ connection to the property; realtor Hugh Russell acted as a marketing and development agent.
As landowners associated with the recorded restrictions, the Boeings participated in a discriminatory system of residential exclusion. Russell handled marketing and development, and the record does not identify William Boeing as the writer of each clause. This dimension of his property business belongs alongside his aviation achievements and charitable work in an account of his life.
Recognition, Death, and the Company That Continued
In the same year that Boeing left the aviation group, he received the 1934 Daniel Guggenheim Medal. Its citation recognized his “pioneering and achievement in aircraft manufacturing and air transport.” The award acknowledged an aviation career in which establishing a company, developing a production enterprise, and extending aircraft use into commercial transport had all been important.
William E. Boeing died on September 28, 1956, after a heart attack aboard his yacht, Taconite. He was 74, three days short of his 75th birthday. In 1966, the National Aviation Hall of Fame honored him with posthumous induction.
The aviation businesses Boeing helped build continued after his departure. His own contribution was to organize, finance, and lead the enterprise, while Westervelt, Wong Tsu, Munter, and others supplied essential technical and practical expertise. Military orders and mail contracts had opened markets; federal reform later reshaped the companies. His career left a substantial mark on aircraft manufacturing and commercial air transport, alongside the documented discrimination attached to his real-estate ventures.
