Berann's career as a panorama cartographer began in 1934 when he won first prize in a competition for a panorama map of the newly opened Großglockner Hochalpenstraße mountain pass road in Austria. His first foreign map followed in 1937 for the Jungfraubahn mountain railroad in Switzerland. After the Second World War, hundreds of further maps followed — for ski resorts, Alpine regions, and tourist destinations across Europe and beyond.
