Occupation: Founder, chairman, and CEO, Morningstar
“I’ve been extremely fortunate in life, and it’s [a] way to give back by funding causes that are making a positive impact in the world,” says this financial research firm founder of his pledge to give half his fortune to charity. Access to information is high on his agenda, too: He’s an investor in Wrapports, which owns the Sun-Times, Reader, and Pioneer Press. And he’s a supporter of his former boss, Bruce Rauner (No. 37), having pledged $100,000 to the Republican’s campaign in December.
