Born on 20th February 1894, Marie Helene Margarethe Batzke, know as Greta, in Straiipitz. She was not Jewish but Evangelical (Protestant). She became Hermann’s second wife in 1930, she was a professional photographer, his first marriage was a rash and unhappy one to Luba Lowinski in January 1926, they divorced in April 1928, a Jew, and as far as I can work out was from a Zionist background, but I have no other real information. If anyone reading this has any information, photographs etc. to add it would be of great interest in building a more complete picture.
