BTW, I was reading after long time also your posts in forum. It was very interesting to read about Kurrol's family. I can confirm, that his fathers name was Julius. So, those persons are from his family.
Quite possible that he got some job in this Institute thanks to her sister. Was it teaching of the math, or smthng else - not sure. But in his application to return to Estonia he was writing, that he is working in this Institute as math teacher. You have made 1 small mistake also in his bio - he moved to Germany already 1924, not 1940 as written there.
Где он подтверждает, что имя отца Курроля было Юлиус, персоны описанные в передыдущих постах в самом деле члены семьи Вальтера К., как пишет сам Курроль в своей биографии, он все же работал учителем математики (или чего-то связанного с ней) в институте. Уехал в Германию в 1924, а не в 40-м, как я писал ранее.
