After having stayed and worked in various locations, in Piedmont, Paris and Florence, Ignazio Porro (1801-1875), a well-known scientist, professor of optics, inventor and precursor in the field of wide-angle lenses, settled in Milan and began teaching at Polytechnic. In Milan in 1865 he also founded a school-workshop specialized in the construction of topographical instruments together with Alessandro Duroni, pioneer of Italian photography, with the name of Filotecnica. Upon Duroni's death in 1871, Angelo Salmoiraghi, a pupil of Porro, already a very young soldier during the third war of independence against the Austrians, entered into a partnership with his master and in 1877, after the death of the latter, took over the factory, which takes the name of La Filotecnica Ing. A. Salmoiraghi, expanding it and broadening the range of products, producing mathematical instruments for drawing, astronomy, meteorology, navigation; among other things, the company built the first Italian sewing machine. During the First World War it supplied war equipment, especially aeronautical, and created a camera intended for aerial photography. In 1927 the company took the name of La Filotecnica Ing. A. Salmoiraghi S.A.. In 1939 Angelo Salmoiraghi died. During the Second World War, much of the production was dedicated to war equipment and the company was therefore considered a war target: the factories were bombed, but at the end of the conflict the company managed to recover immediately. In the 1970s it was bought by Dollond & Aitchinson, together with Viganò, and became Salmoiraghi Viganò, which in 2017 became the property of Leonardo Del Vecchio Luxottica.
