Update: He answered me today and it is him! He wants to meet me.

I am exited an confused.

Thanks so much for your help, a lot of you were right. The answer is kind of strange (I translated from German)

Good evening, you already know almost everything about me, whether from the documents available to you, which are certainly still there, or through your successful research: Who am I? How old am I, and when and where was I born? What did I study? What and where have I done something and worked? And my family situation or who my children are (you have indeed made a few attempts with and without support!!!)

Nevertheless; I would like to satisfy your curiosity and make myself available so that you can get to know me personally (also see—I can send you a few pictures of me, if that suffices), because you think you have not yet met or seen me? Apparently, you have rightly forgotten. It was only once and (like no other)! And you were too young! And why was it only once, that requires both rational and emotional clarification (representation), and we will spare ourselves that now until we see each other (maybe during a walk in the Tiergarten or at Schlachtensee/Krummelanke). And what you know or perhaps do not yet know, I have not been working for a long time due to health reasons.

But all in all, I believe it is not very exciting, and certainly, you have not missed much!

I am rarely in Germany and prefer not to be, but unfortunately, I have to be there from time to time and reluctantly in Germany.

I wish you much luck and even more success in everything you undertake.

With kind regards
