Hollerith Type I 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.

Mining Engineering
Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment bot ...

England And Wales
England and Wales () is one of the three legal jurisdictions of the United Kingdom. It covers the constituent countries England and Wales and was formed by the Laws in Wales Acts 1535 and 1542. The substantive law of the jurisdiction is English law. The devolved Senedd (Welsh Parliament; cy, Senedd Cymru) – previously named the National Assembly of Wales – was created in 1999 by the Parliament of the United Kingdom under the Government of Wales Act 1998 and provides a degree of self-government in Wales. The powers of the Parliament were expanded by the Government of Wales Act 2006, which allows it to pass its own laws, and the Act also formally separated the Welsh Government from the Senedd. There is no equivalent body for England, which is directly governed by the parliament and government of the United Kingdom. History of jurisdiction During the Roman occupation of Britain, the area of present-day England and Wales was administered as a single unit, except f ...

United States Census, 1890
The United States census of 1890 was taken beginning June 2, 1890, but most of the 1890 census materials were destroyed in 1921 when a building caught fire and in the subsequent disposal of the remaining damaged records. It determined the resident population of the United States to be 62,979,766an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census. The data reported that the distribution of the population had resulted in the disappearance of the American frontier. This was the first census in which a majority of states recorded populations of over one million, as well as the first in which multiple citiesNew York as of 1880, Chicago, and Philadelphiarecorded populations of over one million. The census also saw Chicago rise in rank to the nation's second most populous city, a position it would hold until Los Angeles (then 57th) would supplant it in 1990. This was the first U.S. census to use machines to tabulate the collected data. Census ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 "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 1880 census had taken eight years to process. Since the U.S. Constitution mandates a census every ten years to apportion both congressional representatives and direct taxes among the states, a combination of larger staff and faster-recording systems was required. In the late 1880s Herman Hollerith, inspired by conductors using holes punched in different positions on a railway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Record Equipment
Starting at the end of the nineteenth century, well before the advent of electronic computers, data processing was performed using 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 mechanical feeders ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Census Bureau
The United States Census Bureau (USCB), officially the Bureau of the Census, is a principal agency of the U.S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureau is part of the U.S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau's primary mission is conducting the U.S. census every ten years, which allocates the seats of the U.S. House of Representatives to the states based on their population. The bureau's various censuses and surveys help allocate over $675 billion in federal funds every year and it assists states, local communities, and businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, hospitals, transportation infrastructure, and police and fire departments. In addition to the decennial census, the Census Bureau continually conducts over 130 surveys and programs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Shaw Billings
John Shaw Billings (April 12, 1838 – March 11, 1913) was an American librarian, building designer, and surgeon. However, he is best known as the modernizer of the Library of the Surgeon General's Office of the 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 headed the U.S. Census Office's division of Vital Statistics and oversaw statistical compilation of censuses. With Robert Fletcher, Billings developed ''Index Medicus'', a monthly guide to contemporary medicine that ran for 16 months until his retirement at the Medical Museum and Library. At the latter end of his work with the military, Billings aided the United States' Secretary of the Treasury in adjusting the organization of the military h ...
