Munger was not like most main donors, lots of whom Schnur mentioned may be loud, opinionated and stuffed with themselves.

Frustrated with the means Palo Alto faculties taught math, Munger joined the state’s curriculum fee in 2003. He waded into main political spending in 2005, when he gave $100,000 to an unsuccessful redistricting measure backed by former GOP Gov. Arnold Schwarzenegger.
