C-T-R: IBM's Original Three-Letter Acronym
IBM's roots actually predate 1911, but on June 16, 1911, the Computing-Tabulating-Recording Company (C-T-R) was incorporated with the merger of the Tabulating Machine Company (dating from the 1880s), the International Time Recording Company (founded 1900), and the Computing Scale Corporation (founded 1901). C-T-R had 1,300 employees, with the top brass pictured here in the New York headquarters. By 1915, it had $4 million in revenue and nearly 1,700 employees.
