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]
QWERTY The QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a newspaper editor and printer who lived in Milwaukee, Wisconsin. In October 1867, Sholes filed a patent application for his early writing machine he developed with the assistance of his friends Carlos Glidden and Samuel W. SoulÃ©.[1]
