Herman Hollerith (February 29, 1860 – November 17, 1929) was an American statistician and inventor who developed a mechanical tabulator based on punched cards to rapidly tabulate statistics from millions of pieces of data. He was the founder of the Tabulating Machine Company that later merged to become IBM. Hollerith is widely regarded as the father of modern machine data processing.[1] With his invention of the punched card evaluating machine the beginning of the era of automatic data processing systems was marked. His draft of this concept dominated the computing landscape for nearly a century.[2]

Personal life

Herman Hollerith was born the son of C&O Canal, where today there is a commemorative plaque installed by IBM. He died in Washington D.C. of a heart attack.

Electrical tabulation of data

Hollerith tabulating machine and sorting box.[4]

At the urging of John Shaw Billings,[5] Hollerith developed a mechanism using electrical connections to trigger a counter, recording information. A key idea was that data could be encoded by the locations of holes in a card. Hollerith determined that data punched in specified locations on a card, in the now-familiar rows and columns, could be counted or sorted mechanically. A description of this system, An Electric Tabulating System (1889), was submitted by Hollerith to Columbia University as his doctoral thesis, and is reprinted in Randell's book.[6] On January 8, 1889, Hollerith was issued U.S. Patent 395,782,[7] claim 2 of which reads:

The herein-described method of compiling statistics, which consists in recording separate statistical items pertaining to the individual by holes or combinations of holes punched in sheets of electrically non-conducting material, and bearing a specific relation to each other and to a standard, and then counting or tallying such statistical items separately or in combination by means of mechanical counters operated by electro-magnets the circuits through which are controlled by the perforated sheets, substantially as and for the purpose set forth.

Inventions and businesses

Hollerith punched card

Hollerith had left teaching and begun working for the United States Census Bureau in the year he filed his first patent application. Titled "Art of Compiling Statistics", it was filed on September 23, 1884; U.S. Patent 395,782 was granted on January 8, 1889.[8]

Hollerith card puncher used by the United States Census Bureau

Hollerith built machines under contract for the Census Office, which used them to tabulate the 1890 census in only one year.[9] The previous 1880 census had taken eight years. In 1896 Hollerith started his own business when he founded the Tabulating Machine Company. Many major census bureaus around the world leased his equipment and purchased his cards, as did major insurance companies. Hollerith's machines were used for censuses in England, Italy, Germany,[10] Russia, Austria, Canada, France, Norway, Puerto Rico, Cuba, and the Philippines, and again in the 1900 census.[2] To make his system work, he invented the first automatic card-feed mechanism and the first keypunch (that is, a punch operated by a keyboard); a skilled operator could punch 200–300 cards per hour. He also invented a tabulator. The 1890 Tabulator was hardwired to operate only on 1890 Census cards. A plugboard control panel in his 1906 Type I Tabulator allowed it to do different jobs without being rebuilt (the first step towards programming). These inventions were among the foundations of the modern information processing industry and Hollerith's punchcards (though later adapted to encode computer programs) continued in use for almost a century.

In 1911 four corporations, including Hollerith's firm, merged to form the Computing Tabulating Recording Company (CTR).[11] Under the presidency of Thomas J. Watson, it was renamed International Business Machines Corporation (IBM) in 1924.

Notes

His great-grandson, Rt.Rev. Herman Hollerith IV is the Episcopal bishop of the Diocese of Southern Virginia, and another great-grandson, Randolph Marshall Hollerith, is an Episcopal priest in Richmond, Virginia.[13][14]

Hollerith cards were named after the elder Herman Hollerith, as were Hollerith constants (also sometimes called Hollerith strings), an early type of string constant declaration (in computer programming).

as is his son, Herman Hollerith, Jr. (1892-1991). [12]
