Born on this day 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.
