Category:Former IBM Employees
International Business Machines has sold tabulating machines, mainframes, personal computers, consulting services and cloud infrastructure across more than a century of continuous operation. This roster has a clean spine: four consecutive chief executives, running from the near-breakup of the early 1990s through the current bet on hybrid cloud and artificial intelligence. Around that spine the membership splits in two directions, engineers who left IBM early and went on to run other technology companies, and chief executives from outside who joined its board or its vice chairmanship late.
Background
IBM took its present name in 1924 and dominated commercial computing through the mainframe era. By the early 1990s the company was losing money at a scale that raised the question of whether it should be split into independent units, and the decision not to split it is the hinge that the leadership entries below turn on. The modern company sells software, consulting and infrastructure rather than hardware, and its semiconductor research operation is separately important to this category: it trained people who went on to run chip companies elsewhere.
Four chief executives
Lou Gerstner arrived in April 1993 from RJR Nabisco, having earlier held senior positions at American Express and McKinsey and Company. He kept the company whole rather than breaking it up and led it until 2002. Sam Palmisano succeeded him as chairman, president and chief executive, moving the company further out of hardware and into services and software. Ginni Rometty followed in January 2012 as the first woman to lead the company, having been hired as a systems engineer in 1981 and spent nearly four decades there before reaching the top job. Arvind Krishna became chief executive in April 2020, having architected the Red Hat acquisition, and reorganized the company around cloud and artificial intelligence.
Engineers who left
Tim Cook held positions at IBM and then Compaq before joining Apple in 1998, and has been Apple's chief executive since 2011. Lisa Su rose to vice president of IBM's Semiconductor Research and Development Center, where her work centered on silicon-on-insulator manufacturing and chip efficiency, before moving to Freescale Semiconductor and then to Advanced Micro Devices, which she now chairs and runs. Both left the company early enough that IBM appears as a training ground in their biographies rather than as the main event.
The board and the vice chairmanship
The traffic runs the other way as well, and this is the part of the roster most likely to be misread. Martha Pollack is an artificial intelligence researcher who was elected to IBM's board in December 2018, while serving as the fourteenth president of Cornell University. Ramon Laguarta, chairman and chief executive of PepsiCo, was elected to the same board in 2026. Gary Cohn became vice chairman of IBM in January 2021, after the presidency of Goldman Sachs and a term directing the National Economic Council. None of the three built a career inside the company; they arrived at the top of it from somewhere else.
