The Bechtel Family — 8-Decade Defense Infrastructure Dynasty

Lineage: Warren A. Bechtel (founded 1898 as construction contractor) leads to Stephen D. Bechtel Sr. (Hoover Dam Six Companies consortium 1931-1936) leads to Stephen D. Bechtel Jr. (1960-1990 expansion into atomic, defense, Saudi infrastructure) leads to Riley P. Bechtel (1990-2014 GWOT-era Iraq reconstruction, $12.7 billion booked 2002) leads to Brendan Bechtel (2016- current chairman + CEO).

Defense + atomic + civil-infrastructure resume: Hoover Dam Six Companies bridge (1931-1936) leads to Experimental Breeder Reactor I (1949) leads to Dresden Generating Station (1957) leads to AEC reactor construction leads to Naval reactor program leads to Saudi Arabia Vision 2030 leads to 2002-2003 Iraq reconstruction (top GWOT-era heavy civil defense contractor). Privately held — escapes the Securities and Exchange Commission (SEC) public-equity disclosure entirely.

Engine Framing: Bechtel is the unmatched 8-decade-persistence example, demonstrating that defense capital, shielded by sovereign monopsony and Cost-Plus contracting, eliminates the demand-side risk that destroys dynastic wealth in civilian sectors.
