Ingeborg Cramer studied at the Academy of Fine Arts in Vienna from the winter semester of 1931/1932, taking courses at the Master School for Restoration and Technology led by Robert Eigenberger. In 1937, she married the publicist Rafael Spann, son of the ideologist of Austrofascism Othmar Spann. From the end of 1937 until mid-March 1938, she worked as a volunteer without pay at the restoration department of the Picture Gallery of the Kunsthistorisches Museum (KHM). Since her husband was arrested for political reasons on 13 March 1938 and was sent to Gestapo custody in Berlin and then to the Sachsenhausen concentration camp, she had to end her work at the museum and thereafter worked as a freelance painter and restorer. After the release and return of her husband, who was called to the "Wehrmacht" to take part in the French campaign in 1940 and subsequently to work as a management secretary or sole authorised signatory of the double company M.R. Drott KG, Friedrich Krupp Vertriebsgesellschaft / Huber und Drott in Vienna and finally as deputy managing director of the Wiener Neustädter Flugzeugwerke, she applied for paid employment at the KHM in November 1939. A note in the files of the then Kommissarischer Leiter (Commissary Manager) Fritz Dworschak indicates that there were no political objections to her hiring, but she was not accepted for financial reasons. Like her two former colleagues in the restoration workshop of the Picture Gallery of the Kunsthistorisches Museum, Franz Sochor and Eduard Kneisel, she also worked for a time as a restorer for the working staff of Kajetan Mühlmann and was thus involved in the looting of art and cultural property of the Nazi regime in Poland. After 1945, she continued to work as a freelance artist.
