Gerd Börner's haiku appear twice in the World Haiku Review 12/12: in Shintai and in Vanguard.

As far as I see, it was about 20 years ago that Jane Reichhold translated some Dutch and German haiku into English. I found the following German Tongues: Flandrina von Salis, Imma von Bodmershof, Margret
Buerschaper, Sabine Sommerkamp, Ilse Hensel, Ingrid
Grunsky, Ilse von Heywolff-Kullmann, Saskia Ishikawa-Franke, Lia
Frank, Marianne Junghans, Lili Keller-Strittmatter, Gerda
Adelheid Kirmse, Hildegard Loth. Jane Reichhold also tells about a Swiss painter: Conrad Meili, who
had published haiku in Japanese magazines and illustrated many haiku of German speaking origin. Some of the authors named here have been mentioned by Klaus-Dieter Wirth in his essay "Haiku life in Germany - historical background and present situation", written in 2007.
