Age: 71
Company: American Airlines
As American Airlines CEO, the famously hard-charging Crandall steered the company through the deregulation chaos of the '80s, pioneering frequent-flier programs and taking American from a money loser to profitability before retiring in 1998. He has slowed down - some. He says his pace is about half what it was at American. "I'm typically on the road two to three days a week, serving on three public boards - Halliburton, Anixter, and Celestica - and two private ones, and trying to launch an air charter service, called Pogo Air, with new, very light jets." But he says some things haven't changed: "The airline business today remains extremely challenging, as it has been since Kitty Hawk." Crandall says he and his wife, Jan, "are enthusiastic sailors who sail our 48-foot sloop each summer in New England, each winter in the Caribbean - and once across the Atlantic. We spend our winters in Palm City, Fla. Neither of us has gotten very enthusiastic about golf. Jan prefers gardening, and I like working."
