Little is known of Laudon the photographer other than the fact he was an amateur photographer and Baron from Vienna. His more famous relative was most certainly General Gideon Ernst Laudon (1790-1799), an Austrian general from 1790-1799 immortalized in a character drawing by French artist Raphael Jacquemin.
