The money of John Arrillaga Sr., whose name is immortalized in the names of these buildings, is also Silicon Valley money. However, Arrillaga didn't found any start-ups, though he sometimes accepted their shares as rent. Instead, together with Richard Peery, another real estate developer, Arrillaga began in the 196os to buy up gigantic parcels of former farmland in San Jose, Mountain View, Palo Alto, and Sunnyvale and throw up dozens of anonymous office Parks-often without firm commitments or potential tenants. As the orchards and abandoned navy sites increasingly gave way to semiconductor factories and software companies, Arrillaga became enormously wealthy.
