Louis Gerstner, the former chief executive and chairman of IBM, has died at the age of 83, the company said on Sunday. IBM chairman and CEO Arvind Krishna announced Gerstner’s death in an email to employees, without disclosing the cause.
“Lou arrived at IBM at a moment when the company’s future was genuinely uncertain,” Krishna wrote. “His leadership during that period reshaped the company—not by looking backward, but by focusing relentlessly on what our clients would need next.”
Gerstner joined IBM in April 1993 from RJR Nabisco, becoming the first outsider to lead the company, long nicknamed “Big Blue.” Before that, he held senior roles at American Express and consulting firm McKinsey.
During his nine-year tenure, Gerstner is widely credited with rescuing IBM from the brink of bankruptcy. He pivoted the company away from a hardware-heavy model toward business services, reshaped its corporate culture, cut costs, sold non-core assets and launched major share buybacks. When he retired as CEO in 2002, IBM’s stock price was roughly 800% higher than when he had taken the helm.
After leaving IBM, Gerstner became chairman of Carlyle Group, a role he held until his retirement in 2008. He was also a prolific author, writing Who Says Elephants Can’t Dance and co-authoring Reinventing Education: Entrepreneurship in America’s Public Schools.
Gerstner served on the boards of several major companies, including Bristol-Myers Squibb, The New York Times Company, AT&T and Caterpillar. Beyond business, he was deeply committed to public education in the United States, launching initiatives at IBM to bring company technology into schools.
In 1989, he founded Gerstner Philanthropies, including the Gerstner Family Foundation, which supports biomedical research, environmental and education initiatives, and social services in New York City, Boston and Palm Beach County, Florida.
