Henry Laurence Gantt
Henry Laurence Gantt (; May 20, 1861 – November 23, 1919) was an American mechanical engineer and management consultant who is best known for his work in the development of scientific management. He created the Gantt chart in the 1910s. Gantt charts were employed on major infrastructure projects including the Hoover Dam and Interstate highway system and continue to be an important tool in project management and program management. Biography Early life, education and family Gantt was born to a plantation family in Calvert County, Maryland at the outbreak of the American Civil War. When the war ended the family lost their slaves and land, and moved to Baltimore. He graduated from McDonogh School in 1878 and from Johns Hopkins University in 1880, and then returned to the McDonogh School to teach for three years. He subsequently received a Masters of Engineering degree in mechanical engineering from the Stevens Institute of Technology in New Jersey. Henry Gantt married Mary E ...

Bancroft Mills
Bancroft Mills is an abandoned mill complex along Brandywine Creek in Wilmington, Delaware, United States. It has been the site of some of the earliest and most famous mills near Wilmington and was the largest and longest running complex along the Brandywine. History Establishment and Change of Leadership: 1831–1895 Joseph Bancroft (1803–1874), an English immigrant who had worked in the Midlands textile industry, established Bancroft Mills in 1831. The mill was rebuilt following an 1839 flood and was expanded several times, including a large 1895 expansion. By 1880, the mill was already the largest cotton finishing mill in the United States. pp. 199–215 Joseph Bancroft's son Samuel Bancroft, publisher of the Wilmington newspaper ''Every Evening'' and a major philanthropist, took control in the 1880s.

Labor Productivity
Workforce productivity is the amount of goods and services that a group of workers produce in a given amount of time. It is one of several types of productivity that economists measure. Workforce productivity, often referred to as labor productivity, is a measure for an organisation or company, a process, an industry, or a country. Workforce productivity is to be distinguished from employee productivity which is a measure employed at ''individual level'' based on the assumption that the overall productivity can be broken down to increasingly smaller units until, ultimately, to the individual employee, in order be used for example for the purpose of allocating a benefit or sanction based on individual performance (see also: Vitality curve). In 2002, the OECD defined it as "the ratio of a volume measure of output to a volume measure of input". Volume measures of output are normally gross domestic product (GDP) or gross value added (GVA), expressed at constant prices i.e. adjust ...

Bethlehem Steel
The Bethlehem Steel Corporation was an American steelmaking company headquartered in Bethlehem, Pennsylvania. For most of the 20th century, it was one of the world's largest steel producing and shipbuilding companies. At the height of its success and productivity, the company was a symbol of American manufacturing leadership in the world, and its decline and ultimate liquidation in the late 20th century is similarly cited as an example of America's diminished manufacturing leadership. From its founding in 1857 through its 2003 dissolution, Bethlehem Steel's headquarters and primary steel mill manufacturing facilities were based in Bethlehem, Pennsylvania in the Lehigh Valley region of the United States. The company's steel was used in the construction of many of America's largest and most famed structures. Among major buildings, Bethlehem produced steel for 28 Liberty Street, the Chrysler Building, the Empire State Building, Madison Square Garden, Rockefeller Center, and the ...

Midvale Steel
Midvale Steel was a succession of steel-making corporations whose flagship plant was the Midvale Steel Works in Nicetown, Philadelphia, Pennsylvania. The mill operated from 1867 until 1976. In the 1880s, Frederick Winslow Taylor rose through the ranks at Midvale, from lathe operator, to gang boss, to engineer, to chief engineer of the works. During this time he developed the core of his philosophy of scientific management. Overview Midvale produced high-quality steels (including many alloy steels) and for providing the casting, forging, and machining needed to use them in special applications such as heavy artillery (naval, coastal, and field); steam turbines; naval armor plate; and pressure vessels for use in chemical plants (for example, petroleum refineries). Midvale also helped pioneer the steel formulas used in the early automotive industry.. Midvale was never a particularly large company (relative to giants such as Carnegie, Bethlehem, and U.S. Steel), and the fla ...

Frederick Winslow Taylor
Frederick Winslow Taylor (March 20, 1856 – March 21, 1915) was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants. In 1909, Taylor summed up his efficiency techniques in his book '' The Principles of Scientific Management'' which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. His pioneering work in applying engineering principles to the work done on the factory floor was instrumental in the creation and development of the branch of engineering that is now known as industrial engineering. Taylor made his name, and was most proud of his work, in scientific management; however, he made his fortune patenting steel-process improvements. As a result, scientific management is sometimes referred to as ''Taylorism''. Biography Taylor was born in 1856 to a Quaker family in Germantown, Philadelphia, Pennsylvania. Taylor ...

Drafter
A drafter (also draughtsman / draughtswoman in British and Commonwealth English, draftsman / draftswoman or drafting technician in American and Canadian English) is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters use computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. Drafters operate as the supporting developers and sketch engineering designs and drawings from preliminary design concepts. Overview In the past, drafters sat at drawing boards and used pencils, pens, compasses, protractors, triangles, and other drafting devices to prepare a drawing by hand. From the 1980s through 1990s, board drawings were going out of style as the newly developed computer-aided design (CAD) system was released and was able to produce technical drawings at a faster pace. Many modern drafters now use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
