The Wild (Heerbrugg) company was founded in 1921 in Switzerland. The company manufactured different optical instruments, such as surveying instruments, microscopes and instruments for photogrammetry among others. The company changed its name several times, first being known as "Heinrich Wild, Werkstätte für Feinmechanik und Optik", then "Verkaufs-Aktiengesellschaft Heinrich Wild's Geodätische Instrumente", later "Wild Heerbrugg AG", later "Wild Leitz". The company was linked with Leica in 1989, then it became part of Leica Holding B.V. Its subsidiary Leica Geosystems AG became part of the Swedish Hexagon AB Group of companies in 2005.
On 26 April 1921 the company Heinrich Wild, Werkstätte für Feinmechanik und Optik was founded in Heerbrugg by three Swiss personalities:
the surveyor and inventor Heinrich Wild from Glarus
the investor Jacob Schmidheiny from Balgach
and the geologist Dr. Robert Helbling from Flums.
Heinrich Wild (1877–1951), a leading designer of geodetic and astronomical instruments, was born in Switzerland and began his career as an apprentice surveyor. In 1908, having invented a military rangefinder and convinced Zeiss to manufacture it, Wild moved to Jena and became head of GEO, the new Zeiss branch responsible for surveying instruments. Wild returned to Switzerland after the First World War. In 1921, with the help of Swiss financiers, he established a Werkstätte für Feinmechanik und Optik in Heerbrugg, in the Rhine Valley. In the early 1930s, having recognized that he was not cut out to be a factory manager, Wild moved to Zurich, severed his connections with the firm in Heerbrugg, and designed instruments for Kern & Co in Aarau. His old firm became Wild Heerbrugg in 1937. It merged with the optical firm of Ernst Leitz of Wetzlar in 1987, acquired a majority interest in Kern in 1988, was renamed Wild Leitz AG in 1989, and became part of the Leica holding company in 1990.
Starting from 1996 the company was divided gradually again into smaller units. Thus 1996 the Leica Camera AG developed, in October 1997 the Leica Geosystems AG and on 1 April 1998 the Leica Microsystems AG. Leica Geosystems produced—in continuation of Wild Heerbrugg—the geodetic instruments and is the global market leader in this sector as part of the new parent company Hexagon AB.
