IBM Leadership

Who founded IBM, who runs it today, and the multi-CEO modern arc — Akers, Gerstner, Palmisano, Rometty, Krishna — that defined four-plus decades of strategic reinvention. Sourced from the most recent DEF 14A proxy statement filed March 10, 2026 with the SEC, the April 28, 2026 annual-meeting Item 5.07 8-K, and IBM's own leadership page.

Roster row: IBM on /orgs/. Sibling page: IBM Financials (in flight).

Founders — the 1911 merger and the 1924 rename

IBM was incorporated in 1911 as the Computing-Tabulating-Recording Company (CTR), a merger of three predecessor companies orchestrated by financier Charles Ranlett Flint. The largest of the three predecessors was Herman Hollerith's Tabulating Machine Company, whose punched-card system had been used for the 1890 U.S. Census. The company was renamed International Business Machines in 1924 under Thomas J. Watson Sr., who had joined as President in 1914 and ran the company for the next four decades. No living founder remains; the page surfaces Watson Sr. alongside Flint and Hollerith because he is the operational founder of IBM-as-we-know-it.

Charles Ranlett Flint
Incorporator · CTR Co. 1911
Deceased 1934 Then · Industrialist, financier

The financier who engineered the 1911 merger of the Tabulating Machine Company, the International Time Recording Company, and the Computing Scale Company of America into the Computing-Tabulating-Recording Company. Known in his era as the “Father of Trusts” for assembling roll-ups across multiple industries. Never held a CEO role at CTR/IBM; recruited Watson Sr. as general manager in 1914.

Herman Hollerith
Founder · Tabulating Machine Co. 1896
Deceased 1929 Then · Statistician, inventor

Inventor of the electromechanical punched-card tabulator used to process the 1890 U.S. Census. Founded the Tabulating Machine Company in 1896; sold it into the 1911 CTR merger. Remained as a consulting engineer through the early CTR years and retired in 1921. The technology line Hollerith started in 1890 ran in IBM products into the 1970s.

Thomas J. Watson Sr.
President 1914–1949 · CEO 1914–1956
Deceased 1956 Then · NCR sales executive

Recruited to CTR in 1914 from National Cash Register, where he had been a senior sales executive under John Patterson. Renamed CTR to International Business Machines in 1924. Built the punched-card, accounting-machine, and electric-typewriter franchises that carried IBM through the 1950s. Promoted his son Thomas Jr. to President in 1952 and stepped down as CEO in 1956 weeks before his death. Treated here as the operational founder of IBM-as-we-know-it.

The three-card founders strip on this page is the matched-set CoreWeave / Palantir shape adapted for a company old enough that none of its founders are living. The card with Watson Sr. doubles as the bridge into the modern lineage; the Watson dynasty has its own subsection below.

The Watson dynasty — 1914–1971

For 57 of IBM's first 60 years, a Watson ran the company. Thomas Sr. led from 1914 until weeks before his death in 1956; his son Thomas Jr. took the seat and held it for fifteen years, building the System/360 mainframe that defined enterprise computing for a generation. The handoff to T. Vincent Learson in 1971 ended the family-leadership era; every CEO since has been a non-family operator. The dynasty matters here as foundational pre-modern lineage, not as active leadership.

Thomas J. Watson Sr.
1914 – 1956
Recruited as general manager 1914; named President 1915 (held that title through 1949); CEO until May 1956. Renamed the company to International Business Machines in 1924. The 42-year tenure remains the longest in IBM history.
Thomas J. Watson Jr.
1956 – 1971
Succeeded his father as CEO in May 1956. Approved the IBM System/360 program in 1964 — the bet-the-company architectural unification that established the mainframe market IBM dominated for the rest of the century. Retired as CEO in June 1971 following a heart attack; remained Chairman through 1971. Later served as U.S. Ambassador to the Soviet Union (1979–1981) under President Carter.

Krishna's path to the CEO seat ran through Red Hat

The April 2020 Rometty-to-Krishna CEO transition was a strategic-continuity handoff rather than a change-and-pivot. From 2017 to April 2020, Krishna led IBM's Cloud and Cognitive Software business unit, and per the proxy he was “a principal architect of the acquisition of Red Hat, the largest acquisition in the Company's history” — announced October 2018, closed July 2019 at $34 billion. Promoting Krishna in 2020 promoted the architect of the hybrid-cloud strategy that Red Hat was meant to operationalize. He had previously directed IBM Research from 2015 to 2020 and run the Systems and Technology Group before that. He joined IBM in 1990; the 2020 CEO appointment was the culmination of a 30-year internal track record.

Former Red Hat CEO Jim Whitehurst joined IBM as President at the July 2019 deal close, stepped into a Senior Adviser role in July 2021, and left the company shortly after. The President title sat vacant from 2021 until Krishna picked it up in addition to Chairman and CEO — the current proxy lists his combined title as Chairman, President and Chief Executive Officer.

Modern-CEO arc — five eras since 1985

Five CEOs across forty-plus years; each tenure maps to a distinct strategic era. Newest first. Color-coded so the lineage scans at a glance. The earlier (pre-1985) Watson Jr. / Learson / Cary / Opel CEOs are surfaced in the Historical CEO timeline further down.

Arvind Krishna
CEO · Apr 2020 – present
April 2020 – present
Hybrid-cloud-and-AI era. Spun off the managed-infrastructure business as Kyndryl in November 2021 to focus IBM on software and consulting. Launched the watsonx AI platform in 2023. Closed the HashiCorp acquisition in 2025 to extend the Red Hat-anchored hybrid-cloud stack. Combined Chairman + President + CEO since December 2020.
Ginni Rometty
CEO · Jan 2012 – Apr 2020
January 2012 – April 2020
“Strategic Imperatives” / cloud-pivot-first-attempt era. First woman to lead IBM. Branded the company's AI work as Watson and made it the centerpiece of the strategic narrative. Announced the Red Hat acquisition in October 2018 (closed July 2019). The pivot from on-premise services to cloud was steered under Rometty; the explicit hybrid-cloud framing landed under her successor. Remained Chairman through December 2020 to bridge the Krishna transition.
Samuel J. Palmisano
CEO · Mar 2002 – Dec 2011
March 2002 – December 2011
“Smarter Planet” / services-and-software era. Sold the PC business to Lenovo in 2005 and exited commodity hardware; concentrated IBM around services, software, and middleware. Articulated the “Smarter Planet” brand framework in 2008 around analytics and instrumentation. Internal IBM career; succeeded Gerstner from the President-and-COO role.
Louis V. Gerstner Jr.
CEO · Apr 1993 – Mar 2002
April 1993 – March 2002
Turnaround era. The first IBM CEO recruited from outside the company — from RJR Nabisco, before that American Express. Inherited IBM near insolvency after the 1991–1992 losses; declined to break the company up; pivoted the strategy around services and integrated solutions. Documented his nine-year turnaround in Who Says Elephants Can't Dance? (HarperBusiness, 2002).
John F. Akers
CEO · 1985 – Apr 1993
1985 – April 1993
Pre-turnaround era. Internal IBM career; took the CEO seat as the PC industry, client-server computing, and Unix workstations began structurally eroding IBM's mainframe-centric franchise. Reported the largest annual loss in U.S. corporate history at the time ($5 billion in 1992); replaced by Gerstner in April 1993. The Akers era is the necessary prologue to the Gerstner turnaround narrative — the company that had to be rescued had to first be the company that needed rescuing.

Current executive officers

IBM's named executive officers (“NEOs”) for fiscal year 2025 per the March 2026 DEF 14A. The proxy reports 20 directors and executive officers in the beneficial-ownership table; the five NEOs disclosed in the Summary Compensation Table are shown here. Ages are per the proxy. Click any row for the bio detail.

Arvind Krishna
63
Chairman, President and Chief Executive Officer
1990

Joined IBM in 1990. Led the IBM Cloud and Cognitive Software business unit 2017–2020 (the role from which he architected the 2019 Red Hat acquisition) and ran IBM Research as its director 2015–2020. Became CEO and a director in April 2020; elected Chairman in December 2020. Holds outside board seats at Northrop Grumman and at the Federal Reserve Bank of New York (Class B director, 2022 onward). PhD in electrical engineering from the University of Illinois at Urbana-Champaign; undergraduate degree from IIT Kanpur.

James J. Kavanaugh
Senior Vice President, Finance & Operations & Chief Financial Officer

CFO since 2018. The proxy credits the 2025 portfolio optimization and productivity work with ~100 basis points of operating pre-tax margin expansion, $4.5 billion in annual run-rate savings since 2023, $14.7 billion of free cash flow, and the funding of 10 strategic acquisitions in 2025 alongside more than $6 billion returned to stockholders. The longest-tenured of IBM's NEOs in the current cohort.

Gary Cohn
Vice Chairman
2021

Former President and COO of Goldman Sachs (2006–2016) and former Director of the U.S. National Economic Council (2017–2018). Joined IBM as Vice Chairman in 2021. The proxy describes the role as senior-relationship and public-private-partnership-focused: representing IBM in high-level external forums and driving revenue growth through ecosystem and policy engagement. Unusual structural position — not a functional head, but a Section 16 reporting officer compensated at NEO scale.

Robert D. Thomas
Senior Vice President, Software & Chief Commercial Officer

Runs IBM's Software segment and the company's go-to-market organization. The proxy credits him with 9% Software revenue growth at constant currency in 2025 and with scaling the generative-AI book of business in Software to over $2 billion inception-to-date. Heads the watsonx product surface and the AI-anchored portion of IBM's hybrid-cloud strategy.

Anne Robinson
Senior Vice President & Chief Legal Officer

Chief Legal Officer; oversees legal and regulatory affairs across IBM's AI, quantum, M&A, and Consulting work. The proxy highlights her 2025 contributions in streamlining IBM's contracting process and policies and in deploying technology inside the legal organization to accelerate cycle time. Successor to Michelle Browdy, the prior GC who appears in the NEO table for 2021–2023 but not since.

Ages and tenure are as listed in the most recent DEF 14A; an em dash means the field is not separately disclosed in the proxy and the page declines to assert a value from secondary sources. Beyond these five NEOs, the proxy's beneficial-ownership table lists 20 directors and executive officers in aggregate — the additional Section 16 officers (heads of IBM Consulting, Infrastructure, Research, HR, etc.) are publicly visible on IBM's own leadership page. The NEO set is the page's SEC-canonical baseline.

Board of directors

Thirteen directors as of the April 28, 2026 annual meeting. Alex Gorsky is the independent Lead Director. Frederick H. Waddell did not stand for re-election; the By-laws were amended to decrease the board size to 13 effective April 28, 2026 (Item 5.03 8-K).

Former Executive Advisor, Siris Capital Group, LLC
2021

Member of the Directors and Corporate Governance Committee. Former Executive Advisor at Siris Capital Group, the technology-focused private-equity firm. Brings private-equity / cloud-technology perspective from his Siris engagements with cloud-based technology providers.

Committee structure (post April 28, 2026): Audit — Voser (Chair), Farr, Howard, McNabb. Directors and Corporate Governance — Liveris (Chair), Brown, Laguarta, Zollar. Executive Compensation and Management Resources — Buberl (Chair), Miebach, Pollack, Voser. Executive — Krishna (Chair), Gorsky, Liveris, Voser, Buberl. Twelve of the 13 directors are independent under NYSE rules; Krishna is the only management director. The board is elected annually with majority-voting in uncontested elections.

Voting structure — single share class, broadly held, no founder concentration

IBM has a single class of common stock with one vote per share. As of February 10, 2026, there were 938,034,404 shares outstanding and entitled to vote. There is no founder voting concentration: Charles Flint and Herman Hollerith both died in the early 1930s; no descendant of the Watson family holds a controlling position. Institutional concentration is the only material voting block, and it follows the standard large-cap pattern.

The three largest holders disclosed in the most recent proxy:

The combined institutional top-three holds ~24.4% of the float, matching the index-fund concentration pattern that holds across S&P 500 large-caps. IBM's directors and executive officers as a group (20 people) held ~0.16% — non-management directors collectively owned ~263,000 shares as of the FY2025 record date, an average of ~$6.5 million per non-management director. No officer or director individually crosses the 1% threshold.

Structurally, IBM is the matched-set counter-example to every other governance shape on this site:

The broadly-held single-class shape is one of the cleaner versions of that pattern in the AI-adjacent public-company universe and is the cap-table fact behind IBM's long-standing dividend-paying posture (more than 100 consecutive quarterly dividends; an S&P 500 Dividend Aristocrat).

Historical CEO timeline — the full 1914–present lineage

The complete chief executive line from the Watson dynasty onward. The modern arc covered above starts at Akers (1985); this section adds the earlier seats that shaped IBM's pre-modern era. Newest first.

Show the pre-1985 CEO lineage
John R. Opel
1981 – 1985
Internal IBM career. Took the CEO seat as the IBM PC was launched in August 1981 (the first product carrying the IBM brand to ship outside the data center). Set up the architectural decisions — off-the-shelf Intel CPU, off-the-shelf Microsoft operating system — that produced both the PC industry as we know it and the long PC-clone competitive problem IBM never solved.
Frank T. Cary
1973 – 1981
Internal IBM career. The DOJ filed its 1969 antitrust case against IBM during the Watson Jr. / Learson interregnum, and Cary spent most of his tenure managing through it. Drove the development push that produced the System/370, the floppy disk, and the relational-database research at IBM Research that would later become DB2.
T. Vincent Learson
1971 – 1973
Internal IBM career. Briefly bridged the gap between the end of the Watson dynasty and Cary's appointment. The shortest-tenured modern IBM CEO; named to the seat as Watson Jr. retired on health grounds.
Thomas J. Watson Jr.
1956 – 1971
Covered in the Watson dynasty section above. The System/360 era.
Thomas J. Watson Sr.
1914 – 1956
Operational founder of IBM. Covered in the founders and Watson dynasty sections above.

The pre-Akers segment of the page is intentionally lighter on prose than the modern arc — a deep treatment of the Cary or Opel eras is out of scope for a leadership-page recipe whose center of gravity is the proxy's current officer and director rosters. The historical-CEO context is provided so the modern arc reads in its full lineage.

Notable transitions and departures

Senior-officer and board-of-directors transitions since the Krishna CEO appointment. New entries land here as Item 5.02 8-Ks file off-cycle between annual meetings.

Frederick H. Waddell
Director (2012–2026); Chair, Executive Compensation and Management Resources
Apr 28, 2026
Did not stand for re-election; board reduced to 13
Ramon Laguarta
Director (joined)
Mar 1, 2026
Newest director; concurrent Chairman/CEO of PepsiCo
Jim Whitehurst
President (Jul 2019 – Jul 2021); former CEO, Red Hat
Jul 2021
Stepped into Senior Adviser role; later left IBM
Ginni Rometty
CEO (2012–2020); Chairman (2012–2020)
Dec 31, 2020
Retired; author, speaker; board roles outside IBM
Michelle Browdy
Senior Vice President & General Counsel (NEO 2021–2023)
2024
Succeeded by Anne Robinson as CLO

Long-history senior departures (pre-Krishna era) are not enumerated here — a comprehensive ex-officer roster going back to the Watson era would dilute the table's signal. New transitions land here as they file; the matched-set OpenAI and Anthropic leadership departures tables are the precedent for shape.

Federal and public-policy engagement

IBM has been a federal-government IT vendor for more than a century — the 1890 U.S. Census tabulator that Herman Hollerith built is the founding example, and IBM has held a position in U.S. federal computing across every executive-branch administration since. The company holds contracts across the Department of Defense, the intelligence community, civilian agencies, and the federal-civilian-IT-services market that federal tech spending tracks at the aggregate level.

In public-policy terms IBM has been a long-standing participant in the U.S. discussions on export controls, encryption policy, and (most recently) AI regulation. Krishna sits on the board of the Federal Reserve Bank of New York and the U.S.-India Strategic Partnership Forum; Gary Cohn's role as Vice Chairman is explicitly described in the proxy as “public-private partnerships” and senior external engagement. The page does not editorialize on those positions — the load-bearing point is structural: IBM's federal-and-policy footprint is large enough that leadership decisions there are material to the company.
