Herman Hollerith (nonfiction)

Herman Hollerith.

Herman Hollerith (February 29, 1860 – November 17, 1929) 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 consolidated in 1911 with three other companies to form 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.

On September 23, 1884, a patent was filed for Hollerith's tabulating machine. Hollerith's machines were used in the 1890 US Census and in 1924 he and others formed the company that would become IBM.
