Former GE CEO Jack Welch's no frills-and sometimes cutthroat-approach to business helped him make General Electric a $400-billion company by the end of his tenure in 2001. Though criticized for his desire to make GE a more competitive company, Welch is probably most admired for his leadership style. The CEO enjoyed tailored suits, private jets, and an eight-figure salary per year, but that didn't stop him from sitting face-to-face with a team of 15, 150, or 1,500 employees to talk about what they needed to do to make GE a better company. He knew the value of his team and customers, and he knew that strong leadership made for strong employees.
