Dado Moroni also deserves to be mentioned in this thread, as do stride pianists (or better "classic jazz pianists" in a wider sense) Bernd Lhotzky, Louis Mazetier, Rossano Sportiello, Neville Dickie, Mike Goetz, Paolo Alderighi and Henri Chaix and the late and much missed François Rilhac.
And, of course, Chris Hopkins, though US-born, is more German than anything (when I receive his promotional messages from Echoes Of Swing Productions, every word is in German, though, of course, our email exchanges are in English, as I don't know a word of German).
