The woman sitting behind the flowers is Fritz Waechtler's wife Ilse. She was my grade school teacher in the late 60s in Munster/Lager, Germany. I had heard rumors that her husband had been big in the Nazi party. Finding this image conludes my very very long search for any confirmation. It also knocked my socks off.
Thank you for the additional info frickingenius. Now it's already added to the caption.
