Herlango was a maker and distributor of photographic goods in Vienna. The company was formed by the merger of companies named Hrdliczka, Langer and Goldmann (hence Her, Lang, Go) in 1917. Goldmann was a camera-maker. The other partners which formed Herlango made dry plates and printing papers. The pictures at photohistory.at include one of the carpentry shop, suggesting the merged company continued to make some wooden cameras in the 1920s. McKeown lists a number of wood- and metal-bodied folding plate cameras. Herlango is better known, however, as an importer of roll-film cameras made by German companies (including Balda, Kochmann and Zeh) in the 1930s. Several different cameras (by different makers) were sold under the name Renox.
