Herman Hollerith, a clerk at the U S Census Bureau, invented the punch-card tabulator, applying for his first patent in 1884; his punched-card system reigned as the primary large-scale data-processing system until the advent of the electronic digital computer. In 1896 Hollerith formed the Tabulating Machine Company; the British branch, known as the British Tabulating Machine Company, was formed in 1907 and remained connected to its American counterpart until 1949. Hollerith remained head of the Tabulating Machine Company until 1911, when he sold it to industrialist Charles R. Flint, who renamed the company C-T-R. In 1915 Thomas J. Watson became president of the new company, and in 1924 Watson renamed the company International Business Machines (IBM). Origins of Cyberspace 374.
