Berta Schiebel was married in her first marriage to the NSDAP member and Blockleiter (Block Warden) Otto Lug, who came from Munich. Until her husband's death on 5 November 1941, she did not work, but ran the joint household at Am Tabor 22/2/45 in Vienna's 2nd district. Berta Lug did not join the NSDAP, but she was a member of the NS-Frauenschaft (National Socialist Women's League), the Deutsche Arbeitsfront (German Labour Front) and the Nationalsozialistische Volkswohlfahrt (National Socialist People's Welfare). Due to her typewriting skills, she obtained a work contract as an office assistant at the Kunsthistorisches Museum (KHM) in 1942, where she was initially trained in the administrative office and was then assigned to the Coin Cabinet from 5 March 1942. There she met Johann Eichinger, who was divorced from his first wife Maria at the end of 1942, and whom she married on 28 April 1943. After her husband was summoned to the Wehrmacht on 29 April 1943, Berta Eichinger took over his position as a temporary war employee in May 1943. Her employment at the KHM ended on 30 June 1945.
