Voigtländer is an optical company founded by Johann Christoph Voigtländer in Vienna in 1756 and is thus the oldest name in cameras. It produced the Petzval photographic lens (the fastest lens at that time: f/3.7) in 1840, and the world's first all-metal daguerrotype camera (Ganzmetallkamera) in 1841, also bringing out plate cameras shortly afterwards. It set up a branch office in Braunschweig in 1849, moving its headquarters there later. The company issued stock in 1898, and a majority of the shares were acquired by Schering in 1925.
