Donald Wills Douglas Sr.
American aircraft industrialist and aviation pioneer.
Donald Wills Douglas Sr. was an American aircraft industrialist and engineer. He designed and built the Douglas Cloudster, an aircraft intended to be the first to fly non-stop across the United States. Although it failed in that goal, the Cloudster became the first airplane with a payload exceeding its own weight. In 1921, he founded the Douglas Aircraft Company, which later merged with McDonnell Aircraft to form McDonnell Douglas, and ultimately merged with Boeing in 1997. Under his leadership, the company became a dominant force in commercial aviation, engaging in a prolonged rivalry with William Boeing. Douglas gained the upper hand with the revolutionary DC-3 airliner and its military transport version, the C-47; at the start of World War II, his aircraft constituted 80% of all commercial planes in service. However, he fell behind in the jet age and was overtaken by Boeing, retiring in 1957.
Born in Brooklyn, New York, Douglas was an early aviation enthusiast. At 16, he convinced his mother to let him witness the Wright Flyer trials at Fort Myer. He later built model airplanes at the Naval Academy, where he enrolled in 1909. He resigned in 1912 to pursue aeronautical engineering, earning the first Bachelor of Science in Aeronautical Engineering from MIT in 1914. After working for the Connecticut Aircraft Company and as chief engineer for Glenn Martin, he designed the Martin MB-1 bomber. In 1920, he moved to California and started the Davis-Douglas Company with David Davis. After the Cloudster’s failed transcontinental attempt, Davis left, and Douglas founded his own company.
During World War II, Douglas proved prescient, writing before Pearl Harbor that it was the "hour of destiny for American aviation." His company grew from 68 employees in 1922 to the fourth largest business in the United States, contributing to the industrial output that overwhelmed enemy production. He retired in 1957, replaced by his son, and served as honorary chairman of McDonnell Douglas until his death in 1981. His ashes were scattered over the Pacific Ocean.

Lore & Background
Douglas was born in Brooklyn, New York, the second son of an assistant cashier at the National Park Bank. He attended Trinity Chapel School and was of Scottish descent. He built model airplanes in his dormitory at Annapolis, testing them on the grounds and in the armory. He remained another year as an assistant to Professor Jerome Hunsaker. He soon returned to the reformed Glenn L. Martin Company in Cleveland as chief engineer, designing the Martin MB-1 bomber. They had four sons and one daughter including Donald Jr. After an unsuccessful attempt, Davis left, and Douglas founded the Douglas Aircraft Company.
