Teodoro Murer was a camera designer based in Milan, Italy, who made cameras with a company called Duroni. They sold cameras under the names Murer and Salex. In Sweden, the cameras were sold by Hasselblad, and in France by Gaumont[1]. The Duroni company was founded by Alessandro Duroni (1807-1870), c.1835-36, as an optical instrument dealer[2]; Murer joined the company in c.1892.

There are a number of albumen photographs in galleries credited to Murer & Duroni as photographers[3]. Since the original Duroni had died before Murer arrived, this credit must be to the company or a later Duroni. Alessandro Duroni himself has a number of photos credited, including of Guiseppe Garibaldi and Vittorio Emmanuele II, King of Italy 1861-78.
