The "Residenz-Atelier" was a photography studio in Vienna (active from c. 1912–1935), operated—among others—by Berthold Friedmann and his wife Regina Friedmann at Rotenturmstraße 20. Later on Albin Kobe (born in Klagenfurt in 1884, died 1963 in Vienna) took over the management of the studio.  He  had worked – amongst others –  with Hugo Erfurt in Dresden.
