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]
History of tablet computers The tablet computer and the associated special operating software is an example of pen computing technology, and the development of tablets has deep historical roots. The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914.[2] The first publicly demonstrated system using a tablet and handwriting text recognition instead of a keyboard for working with a modern digital computer dates to 1956.[3]
