THE MONEY: Always press shy, and even more so of late, Chernick has not disclosed holdings outside of his El Segundo software firm National Center for Crisis and Continuity Coordination. Results for similar companies were mixed, but other investments likely grew with broader markets.

BUZZ: Born in Los Angeles and raised in rural Canada, founded software firm Candle Corp. in 1976 and sold programs to early customers – including Hughes Aircraft – from a Marina del Rey apartment. Sold the company to IBM in 2004 for $641 million. Went on to found NC4, which makes situational awareness and threat-detection software used by law enforcement agencies and military. Chernick and wife, Joyce, keep a low profile, but have been contributors to Israeli charities and conservative politicians, including Mitt Romney. He was one of the initial funders of conservative blogging company PJ Media, making him a favorite target of liberal blogs.
