Henry Crown (1896-1990)
player
One Chicago sand-and-gravel man muscled his way into control of a giant weapons maker and started an 80-year family grip on the defense business.
Who they are
Henry Crown (1896-1990), founder of Material Service Corporation and the first of the Crown family defense magnates.
What they do
In the engine he is the founding example of the Crown family's long, persistent hold on the US defense industry.
How it works
He founded Material Service Corporation in 1919 (sand, gravel, lime), merged it into General Dynamics in 1959 to gain roughly a 21% controlling family stake, became a GD director and executive-committee chairman, was forced out by Roger Lewis in 1966, then bought back a controlling interest in 1970, ousted Lewis, and installed David S. Lewis.
Why it matters
He matters as the start of a family pattern of staying near the center of defense power for eight decades (the engine scores that persistence at 0.87).
