Son of Boeing founder William Boeing Senior. From The Everett Herald:
William Boeing Jr., son of company's founder, dies at 92
William E. Boeing Jr., a son of aerospace pioneer William Boeing Sr. who championed and remained fascinated by flight throughout his life, has died at age 92.
He died Wednesday night at his home in Seattle, said Mike Bush, a spokesman for The Museum of Flight, which Boeing Jr. helped create. The cause was not immediately known.
Boeing Jr. did not work at his father's company; he pursued a career in commercial real estate. But he nevertheless witnessed how the airplane maker helped transform Seattle from a backwater frontier town to an aerospace hub in the early part of the 20th century, and he became a champion of the industry and aerospace education.
The Museum of Flight is downright amazing - I visited every couple of months as they were building it.
92 is a good run these days - Bill was a class act.
