121 Klic, Karol (Klietsch, Karl)
[br]b. 31 May 1841 Arnau, Bohemia (now Czech Republic)d. 16 November 1826 Vienna, Austria[br]Czech inventor of photogravure and rotogravure.[br]Klic, sometimes known by the germanized form of his name Karl Klietsch, gained a knowledge of chemistry from his chemist father. However, he inclined towards the arts, preferring to mix paints rather than chemicals, and he trained in art at the Academy of Painting in Prague. His father thought to combine the chemical with the artistic by setting up his son in a photographic studio in Brno, but the arts won and in 1867 Klic moved to Vienna to practise as an illustrator and caricaturist. He also acquired skill as an etcher, and this led him to print works of art reproduced by photography by means of an intaglio process. He perfected the process c.1878 and, through it, Vienna became for a while the world centre for high-quality art reproductions. The prints were made by hand from flat plates, but Klic then proposed that the images should be etched onto power-driven cylinders. He found little support for rotary gravure, or rotogravure, on the European continent, but learning that Storey Brothers, textile printers of Lancaster, England, were working in a similar direction, he went there in 1890 to perfect his idea. Rotogravure printing on textiles began in 1893. They then turned to printing art reproductions on paper by rotogravure and in 1895 formed the Rembrandt Intaglio Printing Company. Their photogra-vures attracted worldwide attention when they appeared in the Magazine of Art. Klic saw photogravure as a small-scale medium for the art lover and not for mass-circulation publications, so he did not patent his invention and thought to control it by secrecy. That had the usual result, however, and knowledge of the process leaked out from Storey's, spreading to other countries in Europe and, from 1903, to the USA. Klic lived on in a modest way in Vienna, his later years troubled by failing sight. He hardly earned the credit for the invention, let alone the fortune reaped by others who used, and still use, photogravure for printing long runs of copy such as newspaper colour supplements.[br]Further ReadingObituary, 1927, Inland Printer (January): 614.Karol Klic. vynálezu hlubotisku, 1957, Prague (the only full-length biography; in Czech, with an introduction in English, French and German).S.H.Horgan, 1925, "The invention of photogravure", Inland Printer (April): 64 (contains brief details of his life and works).G.Wakeman, 1973, Victorian Book Illustration, Newton Abbot: David \& Charles, pp. 126–8.LRDBiographical history of technology > Klic, Karol (Klietsch, Karl)

122 Smith, Oberlin
[br]b. 22 March 1840 Cincinnati, Ohio, USAd. 18 July 1926[br]American mechanical engineer, pioneer in experiments with magnetic recording.[br]Of English descent, Smith embarked on an education in mechanical engineering, graduating from West Jersey Academy, Bridgeton, New Jersey, in 1859. In 1863 he established a machine shop in Bridgeton, New Jersey, that became the Ferracute Machine Company in 1877, eventually specializing in the manufacture of presses for metalworking. He seems to have subscribed to design principles considered modern even in the 1990s, "always giving attention to the development of artistic form in combination with simplicity, and with massive strength where required" (bibliographic reference below). He was successful in his business, and developed and patented a large number of mechanical constructions.Inspired by the advent of the phonograph of Edison, in 1878 Smith obtained the tin-foil mechanical phonograph, analysed its shortcomings and performed some experiments in magnetic recording. He filed a caveat in the US Patent Office in order to be protected while he "reduced the invention to practice". However, he did not follow this trail. When there was renewed interest in practical sound recording and reproduction in 1888 (the constructions of Berliner and Bell \& Tainter), Smith published an account of his experiments in the journal Electrical World. In a corrective letter three weeks later it is clear that he was aware of the physical requirements for the interaction between magnetic coil and magnetic medium, but his publications also indicate that he did not as such obtain reproduction of recorded sound.Smith did not try to develop magnetic recording, but he felt it imperative that he be given credit for conceiving the idea of it. When accounts of Valdemar Poulsen's work were published in 1900, Smith attempted to prove some rights in the invention in the US Patent Office, but to no avail.He was a highly respected member of both his community and engineering societies, and in later life became interested in the anti-slavery cause that had also been close to the heart of his parents, as well as in the YMCA movement and in women's suffrage.[br]BibliographyApart from numerous technical papers, he wrote the book Press Working of Metals, 1896. His accounts on the magnetic recording experiments were "Some possible forms of phonograph", Electrical World (8 September 1888): 161 ff, and "Letter to the Editor", Electrical World (29 September 1888): 179.Further ReadingF.K.Engel, 1990, Documents on the Invention of Magnetic Recording in 1878, New York: Audio Engineering Society, Reprint no. 2,914 (G2) (a good overview of the material collected by the Oberlin Smith Society, Bridgeton, New Jersey, in particular as regards the recording experiments; it is here that it is doubted that Valdemar Poulsen developed his ideas independently).GB-N -
