When post-Depression legislation in 1934 mandated the dispersion of the corporation, Boeing sold his interests in the Boeing Airplane Co. but continued to work on other business ventures, as he became one of America’s most successful breeders of thoroughbred horses.
Under William Boeing’s guidance, a tiny airplane manufacturing company grew into a huge corporation of related industries. When post-Depression legislation in 1934 mandated the dispersion of the corporation, Boeing sold his interests in the Boeing Airplane Co. but continued to work on other business ventures, as he became one of America’s most successful breeders of thoroughbred horses. Boeing never lost his interest in aviation, and during World War II he volunteered as a consultant to the company, living just long enough to see the company he started enter the jet age.
