Heinrich Wild (Mitlödi, Canton of Glarus, November 15, 1877 – Baden, Switzerland, December 26, 1951) was a Swiss inventor, designer and founder of Wild Heerbrugg. ==Biography== thumb At 15 years of age, Wild became an apprentice with the engineer Legler in Glarus (hydraulic engineer for the Linth River). He bought a small theodolite, and after a short time independently made expanded measurements of the flow of the river Linth. Later Wild joined the Geometerschule (geometer school) at Winterthur and came in 1899 as a trainee to the Landestopographie (Swisstopo is a popular designation for the Swiss Federal Office of Topography) in Bern. Due to his bad experiences with the high mountain triangulation with a theodolite of conventional design, he tried in 1905 to design a new theodolite with rotable circle with coincidence circle-readings. In 1907 he left the Landestopographie and moved to Jena, Germany, where he joined the company Carl Zeiss to build up a new department for producing geodetic instruments. He began with the development of levelling instruments and designed later also a new theodolite, the Th I. In 1921 Wild returned to Switzerland and founded with Dr. R. Helbling, who operated a measurement office, and with the politician Jacob Schmidheiny, the company Heinrich Wild, Werkstätte für Feinmechanik und Optik (later known as Wild Heerbrugg, Wild-Leitz AG,〔"Wild Heerbrugg und Leitz Wetzlar mit gemeinsamem Namen." New name Wild-Leitz AG from 1989. Neue Zürcher Zeitung, December 28, 1988, p. 30〕 Leica Geosystems, Leica Microsystems, Leica Camera). At this time he developed the first versions of the famous universal theodolite Wild T series〔("WILD Heerbrugg T4 Universal Theodolite", product description by opti-cal )〕 and also the stereo autograph Wild A1 for aerial photo interpretation,〔K. Hildebrand and R. Schlienger: "Scharfer Blick von oben." Neue Zürcher Zeitung, April 24, 1984, p. 69〕 besides a number of other measurement instruments. It may be perhaps typical for the inventors like Wild that he worried little about the financial condition of his company, and this ended finally with the consequence that Wild separated in 1932 from the company he founded, in order to be able to work as a freelance technical designer and inventor. He continued designing up until his death in 1951. Among his designs were the legendary DK1, DKM1, DM2, DKM2, and DKM3, for Kern & Co, Aarau, besides other things. The ETH Zurich honored him with the title Dr. honoris causa in 1930. His biography was published in the Historical Dictionary of Switzerland〔(Wolfgang Göldi: "Heinrich Wild". Historisches Lexikon der Schweiz, Biography (in German) )〕 as well as by the ETHZ.〔(Biography of Heinrich Wild, Swiss Geodetic Commission, published by ETHZ (in German) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heinrich Wild」の詳細全文を読む スポンサード リンク
