Historia de la Maquina Tabuladora (Herman Hollerith)


Herman Hollerith

Herman Hollerith was an American inventor who developed an electromechanical punched card tabulator to assist in summarizing information and, later, accounting. He was the founder of the Tabulating Machine Company that was amalgamated in 1911 with three other companies to form a fifth company, the Computing-Tabulating-Recording Company later renamed IBM. 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 dominated that landscape for nearly a century.
