My connection to Karl May

It is said that each person knows each other over at most six corners. The same applies even to me and Karl May:

In 2008(?) I met Lothar Schmid without knowing it, as he - much in his usual humor - promised to come to a problemist meeting. He did, but only ate lunch there, without showing up at the actual meeting.

Lothar Schmid was the grandson of the Karl-May-Verlag founder E.A. Schmid, who in turn founded it together with Karl May's widow Klara May.

So here is the connection:
Me -> Lothar Schmid -> E.A. Schmid -> Klara May -> Karl May

If this short not-meeting doesn't count, you can add a lot of people between me and Lothar Schmid, for example Manfred Mädler with whom I conversed some years ago. Six corners, indeed.
