Hollerith Automatic Feed Tabulator
Herman Hollerith (February 29, 1860 – November 17, 1929) was a German-American statistician, inventor, and businessman who developed an electromechanical tabulating machine for punched cards to assist in summarizing information and, later, in accounting. His invention of the punched card tabulating machine, patented in 1884, marks the beginning of the era of mechanized binary code and semiautomatic data processing systems, and his concept dominated that landscape for nearly a century. Hollerith founded a company that was amalgamated in 1911 with several other companies to form the Computing-Tabulating-Recording Company. In 1924, the company was renamed "International Business Machines" (IBM) and became one of the largest and most successful companies of the 20th century. Hollerith is regarded as one of the seminal figures in the development of data processing. Biography Herman Hollerith was born in Buffalo, New York, in 1860, where he also spent his early childhood.

Rhineland-Palatinate
Rhineland-Palatinate ( , ; ; ; ) is a western state of Germany. It covers and has about 4.05 million residents. It is the ninth largest and sixth most populous of the sixteen states. Mainz is the capital and largest city. Other cities are Ludwigshafen am Rhein, Koblenz, Trier, Kaiserslautern, Worms, and Neuwied. It is bordered by North Rhine-Westphalia, Saarland, Baden-Württemberg and Hesse and by France, Luxembourg and Belgium. Rhineland-Palatinate was established in 1946 after World War II, from parts of the former states of Prussia (part of its Rhineland and Nassau provinces), Hesse ( Rhenish Hesse) and Bavaria (its former outlying Palatinate kreis or district), by the French military administration in Allied-occupied Germany. Rhineland-Palatinate became part of the Federal Republic of Germany in 1949 and shared the country's only border with the Saar Protectorate until the latter was returned to German control in 1957.

Tabulating Machine
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the U.S. Census, 1890, 1890 U.S. Census. Later models were widely used for business applications such as accounting and inventory control. It spawned a class of machines, known as unit record equipment, and the data processing industry. The term "supercomputer, Super Computing" was used by the ''New York World'' newspaper in 1931 to refer to a large custom-built tabulator that IBM made for Columbia University. 1890 census The U.S. Census, 1880, 1880 census had taken eight years to process. Since the U.S. Constitution mandates a census every ten years to apportion both United States congressional apportionment, congressional representatives and direct taxes among the U.S. states, states, a combination of larger staff and faster-recording systems was required.

Unit Record Equipment
Starting at the end of the nineteenth century, well before the advent of electronic computers, data processing was performed using Electromechanics, electromechanical machines collectively referred to as unit record equipment, electric accounting machines (EAM) or tabulating machines. Unit record machines came to be as ubiquitous in industry and government in the first two-thirds of the twentieth century as computers became in the last third. They allowed large volume, sophisticated data-processing tasks to be accomplished before electronic computers were invented and while they were still in their infancy. This data processing was accomplished by processing punched cards through various unit record machines in a carefully choreographed progression. This progression, or flow, from machine to machine was often planned and documented with detailed flowcharts that used standardized symbols for documents and the various machine functions. All but the earliest machines had high-speed me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brian Randell
Brian Randell (born 1936) is a British computer scientist, and emeritus professor at the School of Computing, Newcastle University, United Kingdom. He specialises in research into software fault tolerance and dependability, and is a noted authority on the early pre-1950 history of computing hardware. Biography Randell was employed at English Electric from 1957 to 1964 where he was working on compilers.

John Shaw Billings
John Shaw Billings (April 12, 1838 – March 11, 1913) was an American librarian, building designer, and surgeon who modernized the Library of the Surgeon General's Office in the United States Army. His work with Andrew Carnegie led to the development and his service as the first director of the New York Public Library. Billings oversaw the building of the Surgeon General's Library, which was the nation's first comprehensive library for medicine. Because of his approach to improving public health and hospitals, Billings was asked to head the United States Census Bureau, U.S. Census Bureau's Vital statistics (government records), Vital Statistics division, where he oversaw statistical compilation of censuses. With Robert Fletcher, Billings developed ''Index Medicus'', a monthly guide to contemporary medicine that was published for sixteen months until Billings' retirement from the Medical Museum and Library.

Chesapeake And Ohio Canal
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the Grand Old Ditch, operated from 1831 until 1924 along the Potomac River between Washington, D.C., and Cumberland, Maryland. It replaced the Patowmack Canal, which shut down completely in 1828, and could operate during months in which the water level was too low for the former canal. The canal's principal cargo was coal from the Allegheny Mountains. Construction began in 1828 on the canal and ended in 1850 with the completion of a stretch to Cumberland, although the Baltimore and Ohio Railroad had already reached Cumberland in 1842. The canal had an elevation change of which required 74 canal locks, 11 aqueducts to cross major streams, more than 240 culverts to cross smaller streams, and the Paw Paw Tunnel. A planned section to the Ohio River in Pittsburgh was never built. The canal is now maintained as the Chesapeake and Ohio Canal National Historical Park, with a trail that follows ...
