Typewrote
A typewriter is a mechanical or electromechanical machine for typing characters. Typically, a typewriter has an array of keys, and each one causes a different single character to be produced on paper by striking an inked ribbon selectively against the paper with a type element. Thereby, the machine produces a legible written document composed of ink and paper. By the end of the 19th century, a ''person'' who used such a device was also referred to as a ''typewriter''. The first commercial typewriters were introduced in 1874, but did not become common in offices in the United States until after the mid-1880s. The typewriter quickly became an indispensable tool for practically all writing other than personal handwritten correspondence. It was widely used by professional writers, in offices, in business correspondence in private homes, and by students preparing written assignments. Typewriters were a standard fixture in most offices up to the 1980s. After that, they began to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Keyboards
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Keyboard keys (buttons) typically have a set of characters engraved or printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce characters ( letters, numbers or symbols), other keys (such as the escape key) can prompt the computer to execute system commands. In a modern computer, the interpretation of key presses is generally left to the software: the information sent to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typographer (typewriter)
The typographer was an early typewriter A typewriter is a Machine, mechanical or electromechanical machine for typing characters. Typically, a typewriter has an array of Button (control), keys, and each one causes a different single character to be produced on paper by striking an i ... invented by William Austin Burt. Intended to aid in office work, the machine worked by using a lever to press characters onto paper one at a time. It was the first typewriting machine to be patented in the United States, although Pellegrino Turri had made one in Italy in 1808. Perhaps because of its slow speed, or because there was not yet a wide market for typewriters, it was not a commercial success. The working model that Burt constructed for his 1829 patent was destroyed in the 1836 Patent Office fire.

William Austin Burt
William Austin Burt (June 13, 1792 – August 18, 1858) was an American inventor, legislator, surveyor, and millwright. Burt was born in Worcester, Massachusetts, and lived in Michigan from 1822 until his death in 1858. He was a member of the Michigan Territorial Legislature, 1826–7. He served as Mount Vernon's first postmaster from 1832 to 1856. He was a Macomb County Circuit Court judge in 1833, a state legislator in 1853, and a deputy U.S. surveyor from 1833 to 1853. While surveying, he won acclaim for his accurate work on public land surveys. In 1857, Burt moved to Detroit, where he died a year later. Among Burt's numerous inventions were the typographer in 1829, which was a predecessor to the typewriter. He also invented the solar compass, a surveying tool used in the Michigan Survey, employed in regions which had an abundance of minerals that would interfere with accurate readings when using ordinary instruments. While out surveying on September 19, 184 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

He also invented carbon paper to provide the ink for his machine. According to another version, the machine was invented in 1802 by Agostino Fantoni from Fivizzano, nephew of the Italian poet Labindo, to help his blind sister, while Turri merely improved Fantoni's machine and invented the carbon paper in 1806.

Blindness
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking. The terms ''low vision'' and ''blindness'' are often used for levels of impairment which are difficult or impossible to correct and significantly impact daily life. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems. The most common causes of visual impairment globally are uncorrected refractive errors (43%), cataracts (33%), and glaucoma (2%). Refractive errors include near-sightedness, far-sightedness, presbyopia, and astigmatism (eye), astigmatism. Cataracts are the most common cause of blindness. Other disorders that may cause visual problems include age-related macular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kingdom Of Great Britain
Great Britain, also known as the Kingdom of Great Britain, was a sovereign state in Western Europe from 1707 to the end of 1800. The state was created by the 1706 Treaty of Union and ratified by the Acts of Union 1707, which united the Kingdom of England (including Wales) and the Kingdom of Scotland to form a single kingdom encompassing the whole island of Great Britain and its outlying islands, with the exception of the Isle of Man and the Channel Islands. The unitary state was governed by a single Parliament of Great Britain, parliament at the Palace of Westminster, but distinct legal systems—English law and Scots law—remained in use, as did distinct educational systems and religious institutions, namely the Church of England and the Church of Scotland remaining as the national churches of England and Scotland respectively. The formerly separate kingdoms had been in personal union since the Union of the Crowns in 1603 when James VI of Scotland became King of England an ...
