Salmoiraghi (Filotecnica Ing. A. Salmoiraghi S.A.) was an optical company in Milan. According to Storia della Fotografia, the firm began as a laboratory/workshop making very limited numbers of experimental instruments, started by scientist and inventor Ignazio Porro.[1] Alessandro Duroni (later of Murer & Duroni) was involved in the establishment. Angelo Salmoiraghi joined Porro after Duroni died, and re-ordered the establishment as a more commercial venture when Porro himself died in 1875. The company made navigational, surveying, astronomical and other instruments,[2] and increasingly, photographic optics, including an aerial camera for military use in the First World War. Salmoiraghi died in 1939; the company name remains in the Italian retail opticians Salmoiraghi & Vigano.
