- Q5487157 abstract "Frank Haven Hall (/hɑːll/ HAH-l; 9 February 1841 – January 3, 1911) was an American inventor, author, academic administrator, and theoretical structuralist. He invented the first successful mechanical point writer and developed major functions of modern day typography with kerning and tracking. His development of the Hall Braille Writer, in 1892, revolutionized Braille communication by dramatically speeding up the rate by which one could produce Braille characters. His research and development in the tactile writing system used by people who are blind or visually impaired, has been hailed as "the most innovative development of communications for the blind in the 19th century." His main research focused on specialized machines with differentiated keys, one for each dot in the Braille cell. He also created the stereo typewriter which produced copies faster and cheaper, derivative of inventions by Danish counterpart Rasmus Malling-Hansen, in 1893.Early in his engineering career, Hall focused on experimental typefaces, typesetting, type design, and display configurations with ink on paper and metal placings. His first showing of his inventions occurred at the Chicago World Fair in which he displayed his newly invented and developed, stereotyper, in 1893. His technical innovations spawned a pioneering of non-impressed metal holdings, which lead to the termed, "Battle of the Dots", between the traditional New York Point and his typographic structure. He adapted the stereotyper and Braille writer, subsequently creating a new precedent for blind education and information technology. It quickly spread around the country and was established on a global scale soon after.He went on become successful academic administrator in Illinois and served as the Superintendent of the Illinois Institution for the Blind He wrote numerous publications on mathematics and structural theory that were widely used in the United States during the 1890s and 1910s. In total he has published 20 widly-circulated mathematical and structural studies and textbooks. He served as the official Illinois state delegate to the Farmers' National Congress in 1908 and the National Farm Land Congress in 1909, and was a member of the National Conservation Commission. He later founded the first boarding school for the blind in the United States. He was widely known for his publications of Hall's Mathematical Series, an established educational series on algebraic manipulation and arithmetic.".
