Jack Welch was a chemical engineer for General Electric in the 1960s. In 1981 he became the youngest GE CEO to date at the age of 45. Under his power, GE grew to a market value of $500 million, with many calling his leadership abrasive but necessary. Within just a few years billions of dollars had been made or saved through sales and job layoffs, setting the stage for a string of company takeovers. Welch has now passed away at the age of 84. His wife commented how despite his business success and work, he was able to still be a loving father and husband to their family.
