Founding Story

In the 1880s Herman Hollerith built electric punch-card tabulating machines to speed up the US Census; they processed the 1890 count far faster than hand tallying. In 1911 financier Charles Ranlett Flint merged Hollerith's Tabulating Machine Company with the International Time Recording Company, the Computing Scale Company of America, and Bundy Manufacturing to form the Computing-Tabulating-Recording Company (CTR). Thomas J. Watson Sr. joined in 1914, focused the company on tabulating machines and a disciplined sales force, and renamed it International Business Machines in 1924.

Background

Charles Ranlett Flint was a prominent New York financier, consolidator, and deal-maker in the late 19th and early 20th centuries. Known as the 'Father of Trusts,' Flint specialized in merging small companies into larger entities across industries including rubber, starch, and computing. He had experience in international trade, arms dealing, and industrial consolidation, skills that made him effective at identifying undervalued businesses and combining them for scale. Flint did not have a technical background in computing or tabulation; his contribution was financial engineering and corporate organization.

Role at International Business Machines Corporation

IBM possesses the most historic, foundational founding story in the entire history of modern computing, tracing its corporate lineage back to the genesis of data processing in the late 19th century and the aggressive, well-known leadership of a single, strong salesman. The foundational origins of the conglomerate trace back to the 1880s and the invention of the primitive punched card tabulating machine by Herman Hollerith (which was used to process the 1890 US Census). In 1911, Hollerith's company merged with several other disparate manufacturing companies (making meat slicers, commercial scales, and employee time clocks) to form the Computing-Tabulating-Recording Company (CTR). The definitive pivot that created the modern empire occurred in 1914, when the board hired Thomas J. Watson Sr. as General Manager. Watson was an effective, intensely aggressive former sales executive at the National Cash Register Company (NCR). Watson transformed CTR. He instilled a fanatic corporate culture centered entirely on customer service and a professional, immaculately dressed sales force (the famous IBM blue suit). He famously coined the ubiquitous corporate motto: 'THINK.' Recognizing that the true future of the company lay entirely in the lucrative tabulating machines (rather than meat slicers), Watson focused the company's engineering resources entirely on data processing. In 1924, reflecting his global ambition, he renamed the company International Business Machines (IBM). Under Watson's dictatorial rule, IBM dominated the punch-card era, providing the foundational bureaucratic infrastructure for Franklin D. Roosevelt's New Deal (processing millions of Social Security records). This disciplined, strong corporate culture established the foundational architecture that eventually allowed IBM to dominate the dawn of the digital computer age in the 1960s.

Charles Ranlett Flint was born in 1850 in Thomaston. Education: New York University Tandon School of Engineering.

Who Founded IBM? FAQ

Who founded IBM and in what year was the company originally established?

IBM was founded on June 16, 1911, by financier and trust organizer Charles Ranlett Flint in Endicott, New York, under the original name Computing-Tabulating-Recording Company (C-T-R).

Which companies merged to create C-T-R in 1911?

Charles Ranlett Flint merged four companies: the Tabulating Machine Company (founded by punch-card inventor Herman Hollerith), the International Time Recording Company, the Computing Scale Company of America, and the Bundy Manufacturing Company.

Who was Herman Hollerith and what was his major punch-card invention?

Herman Hollerith was an American inventor who developed electromechanical punch-card tabulating machines to process the 1890 U.S. Census in just six months (saving the government $5 million). Hollerith's punch cards became the foundational data storage medium for modern computing.

When and why was C-T-R renamed International Business Machines (IBM)?

In February 1924, President Thomas J. Watson Sr. renamed the Computing-Tabulating-Recording Company to 'International Business Machines' (IBM) to reflect the company's growing global expansion across Europe, Latin America, and Asia.

What was Thomas J. Watson Sr.'s famous 'THINK' motto and where did it originate?

Watson coined the motto 'THINK' in 1911 while an executive at NCR, bringing it to IBM. Watson placed 'THINK' signs in every office, factory, and notebook, asserting that thought, foresight, and intellect were the ultimate drivers of human progress.

What early social benefits did IBM pioneer for industrial workers in the 1930s?

During the Great Depression, Thomas J. Watson Sr. refused to lay off workers, keeping factories running to build machine inventories. IBM became one of the first major corporations to introduce paid vacations, group life insurance, and survivor benefits for factory employees.

How did IBM assist the U.S. Government with the landmark Social Security Act in 1935?

In 1935, when the U.S. enacted the Social Security Act, IBM was the only company with the manufacturing capacity and tabulating technology capable of maintaining employment and wage records for 26 million Americans, cementing its role as the trusted partner of governments worldwide.

How is the founding legacy of IBM commemorated today?

IBM's founding heritage is honored at the Thomas J. Watson Research Center in Yorktown Heights, New York, through the preservation of historic punch-card archives, and in the enduring scientific contributions of IBM Fellows worldwide.

Who founded IBM?

The company was officially organized by financier Charles Ranlett Flint in 1911. However, the true "founder" of the modern IBM culture is Thomas J. Watson. He took over in 1914 and instituted an incredibly strict, highly professional corporate culture (dark suits, white shirts) and coined the legendary corporate motto: "THINK".
