As only the third CEO of the retail giant Wal-Mart, Lee Scott Jr. maintained a low profile while steering the company to increased good fortune. Scott joined Wal-Mart in 1979, overseeing the company's trucking fleet. He gained a reputation as a master of logistics, moved into sales and merchandise, and became CEO in 2000. An aggressive businessman and a risk-taker, Scott managed to increase company profits at a time when many retailers were forced to scale down and cut back.
