Who created the typewriter? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Who created the typewriter? Typewriters are a very modern invention and are still being improved. But did you know that the typewriter was patented by the Englishman Henry Mill back in 1714? This typewriter, however, was never made. The first typewriters were patented as a means of helping the blind. In the United States, the first typewriter was patented by William Burt in 1829. It was called the "typewriter for the blind", and today there is no analogue of this type of typewriter. In 1833, the Frenchman Xavier Progen invented a typewriter with character keys and levers for each character. You can see that many inventors contributed to the development of the typewriter. In 1843, the American Charles Thurber patented a typewriter in which the character keys were located around a copper wheel mounted on an axle. It was scrolled by hand to the required letter, and the letter covered with paint slapped on the paper. However, this operation was too slow for such a machine to come into use. The next step forward was made in 1856, when a typewriter appeared in which the keys were arranged in a circle, and the blow was made at the same point, in the center. This principle is used in modern machines. The first typewriter that could be practically used and at the same time produced in large quantities was designed by three American inventors: Christopher Scholes, Samuel Soule and Carlos Glidden. In 1873 they improved it to such a level that it could already be sold. This typewriter had many distinctive features that made it similar to modern ones: paper inserted around a rubber roller, ink ribbon, reversible (with forward and reverse) ribbon spools, a moving carriage. Over time, other improvements have been added, and today we have portable, silent, and electric typewriters. However, now many prefer machines with memory. Author: Likum A. Random interesting fact from the Great Encyclopedia: Why did Bulgaria issue a coin with a face value of 1,95583 leva? In 1999, Bulgaria equated its currency lev to the German mark. A few years later, the marks were replaced by the euro at the rate of 1,95583 marks = 1 euro, and the lev became pegged to the euro in the same ratio. When the country's accession agreement to the European Union was signed in 2005, the Bulgarian National Bank issued a commemorative coin with a unique denomination of 1,95583 leva as a symbol of Bulgaria's desire to adopt the euro in the future as well.
