Inventions and Businesses
Hollerith had left teaching and begun working for the United States Census Office 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. Patents 395,781 395,782 and 395,783 was published in the Scientific American on January 18, 1889.
Hollerith built machines under contract for the Census Office, which used them to tabulate the 1890 census in only one year. The 1880 census had taken eight years. Hollerith then started his own business in 1896, founding the Tabulating Machine Company. Most of the major census bureaus around the world leased his equipment and purchased his cards, as did major insurance companies. To make his system work, he invented the first automatic card-feed mechanism and the first key punch (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.
In 1911 four corporations, including Hollerith's firm, merged to form the Computing Tabulating Recording Company (CTR). Under the presidency of Thomas J. Watson, it was renamed International Business Machines Corporation (IBM) in 1924.

Famous quotes containing the words inventions and/or businesses:
“By whatever means it is accomplished, the prime business of a play is to arouse the passions of its audience so that by the route of passion may be opened up new relationships between a man and men, and between men and Man. Drama is akin to the other inventions of man in that it ought to help us to know more, and not merely to spend our feelings.”
—Arthur Miller (b. 1915)
“One of the first businesses of a sensible man is to know when he is beaten, and to leave off fighting at once.”
—Samuel Butler (1835–1902)
