Electric Typewriter
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. At the end of the nineteenth century, the term 'typewriter' was also applied to a ''person'' who used such a device. The first commercial typewriters were introduced in 1874, but did not become common in offices 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, business correspondence in private homes, and by students preparing written assignments. Typewriters were a standard fixture in most offices up to the 1980s. Thereafter, they began to be largely supplanted by personal computers running word processing software. Nevertheless, typewri ...

Underwood Typewriter Company
The Underwood Typewriter Company was an American manufacturer of typewriters headquartered in New York City, with manufacturing facilities in Hartford, Connecticut. Underwood produced what is considered the first widely successful, modern typewriter. By 1939, Underwood had produced five million machines. History From 1874, the Underwood family made typewriter ribbon and carbon paper, and were among a number of firms who produced these goods for Remington. When Remington decided to start producing ribbons themselves, the Underwoods opted to manufacture typewriters. The original Underwood typewriter was invented by German-American Franz Xaver Wagner, who showed it to entrepreneur John Thomas Underwood. Underwood supported Wagner and bought the company, recognizing the importance of the machine. The Underwood Number 5 launched in 1900 has been described as "the first truly modern typewriter." Two million of these typewriters had been sold by the early 1920s, and its sales “ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pellegrino Turri
Pellegrino Turri (1765–1828), an Italian inventor, invented a mechanical typing machine, one of the first typewriters, at the start of the 19th century (conflicting accounts suggest 1801, 1806 or 1808) for his blind friend Countess Carolina Fantoni da Fivizzano. He also invented carbon paper Carbon paper (originally carbonic paper) consists of sheets of paper which create one or more copies simultaneously with the creation of an original document when inscribed by a typewriter or ballpoint pen. History In 1801, Pellegrino Turri, ... 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 impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment– visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. Low vision is a functional definition of visual impairment that is chronic, uncorrectable with treatment or correctable lenses, and impacts daily living. As such low vision can be used as a disability metric and varies based on an individual's experience, environmental demands, accommodations, and access to services. The American Academy of Ophthalmology defines visual impairment as the best-corrected visual acuity of less than 20/40 in the better eye, and the World Health Organization defines it as a presenting acuity of less than 6/12 in the better eye. The term blindness is used for complete or nearly complete vision loss. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Mill
Henry Mill (c. 1683–1771) was an English inventor who patented the first typewriter in 1714. He worked as a waterworks engineer for the New River Company, and submitted two patents during his lifetime. One was for a coach spring, while the other was for a "Machine for Transcribing Letters". The machine that he invented appears, from the patent, to have been similar to a typewriter, but nothing further is known. Other early developers of typewriting machines include Pellegrino Turri. Many of these early machines, including Turri's, were developed to enable the blind to write. Life The eldest son of Andrew and Dorothy Mill, was born in 1683 or 1684; according to his epitaph he was a relation of Sir Hugh Myddelton. He obtained an appointment about 1720 as engineer to the New River Company. Mill's obituary notice in the ''Gentleman's Magazine'' states that he erected waterworks at Northampton. He was employed by Sir Robert Walpole to carry out the water supply for Houghton Hall. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
