What year was Boeing founded?

Boeing was founded in 1916, marking a significant moment in aviation history. The company was established by William Boeing in Seattle, Washington, primarily to manufacture seaplanes. The foundation of Boeing is pivotal as it represents the beginnings of one of the world's largest and most influential aerospace manufacturers. Since its inception, Boeing has grown to become a leader in commercial aviation and defense, pioneering innovations in aircraft design and manufacturing.

The other years mentioned do not align with Boeing's actual founding date. For example, 1910 was too early, as the aviation industry was still in its infancy. The year 1920 came after the establishment of Boeing, and 1930 is well beyond the company's founding and represents a period during which Boeing was already an established player in the aviation market.
