when was the first lettered machine - like typewriter invented and by whom
Typographer (typewriter) The typographer was patented on July 23, 1829, as U.S. patent No. 5581X.[3] United States Patent Office documents describe Burt's American machine as "the actual construction of a type writing machine for the first time in any country".[4] It was the first practical typewriting machine ever made in America,[5] although Pellegrino Turri had made one in Italy in 1808.[6] The patent gave Burt the full exclusive rights to his new typewriter machine for 14 years, including vending or selling to others any or all of these rights as he saw fit, signed by President Andrew Jackson.[1]
Printing press Johannes Gutenberg, a goldsmith by profession, developed, circa 1439, a printing system by adapting existing technologies to printing purposes, as well as making inventions of his own. Printing in East Asia had been prevalent since the Tang dynasty,[3][4] and in Europe, woodblock printing based on existing screw presses was common by the 14th century. Gutenberg's most important innovation was the development of hand-molded metal printing matrices, thus producing a movable type based printing press system. His newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities. Movable type had been hitherto unknown in Europe. In Europe, the two inventions, the hand mould and the printing press, together drastically reduced the cost of printing books and other documents, particularly in short print runs.
