Under his leadership, the company’s revenue grew from $US25 billion to $US130 billion, its income from $US1.5 billion to $US15 billion, and its market capitalisation from $US14 billion to $US400 billion.

In 1999, Fortune named Welch the “Manager of the Century,” both for his work making GE among the world’s most valuable companies and for his influence as a managerial thinker.

As a manager, Jack approached each business with a “fix, close or sell” attitude. He presided over almost 1,000 deals during his time as CEO.

Despite his transformative impact on GE’s value, Welch fired over 100,000 people during his first five years as CEO, earning him the nickname of “Neutron Jack,” which he despised.

His differentiation system, also known as “rank and yank,” created a competitive internal corporate structure, in which the top 20% of managers received benefits and the bottom 10% got fired.

Jack transformed his personal wealth as well. When he first began working at GE in 1960 as a chemical engineer, he made $US10,500 a year, and by the time he left the company in 2001, he was making $US16 million a year.

Jack received a $US417 million severance package when he retired, which is one of the largest that any American CEO has ever received.

Shortly after his retirement, Jack and his then wife, Jane, underwent a contentious divorce. Their legal battle revealed both an affair Jack had with Suzy Wetlaufer, who he later married in 2004, and lavish perks GE had been giving the retired executive.

After his retirement, Jack wrote multiple books, taught as a visiting professor at MIT’s Sloan School of Management, and often appeared on TV as a business commentator.
