Hollerith, Herman hō´lərĭth [key], 1860–1929, American inventor, b. Buffalo, N.Y. After graduating from Columbia Univ. (B.S., 1879), he worked on the U.S. Census of 1880. Intrigued by the problem of tabulating vast amounts of data, he developed over the next several years a card that could be represent data through a series of punched holes and a number of machines for punching and tabulating the cards. In 1896 Hollerith founded the Tabulating Machine Company which, through mergers and acquisitions, grew into the International Business Machines Company.
