Herman Hollerith

Herman Hollerith (February 29, 1860 – November 17, 1929) is an American inventor who developed an electromechanical punched card tabulator to assist in summarizing information and, later, accounting.

Heis the founder of the Tabulating Machine Company that is amalgamated (via stock acquisition) in 1911 with three other companies to form a fifth company, the Computing-Tabulating-Recording Company, which is renamed IBM in 1924.

Hollerith is regarded as one of the seminal figures in the development of data processing.

His invention of the punched card tabulating machine marks the beginning of the era of semiautomatic data processing systems, and his concept will dominate that landscape for nearly a century.
