George Posca, who was he?

[ErlingI]

A small update:
I have updated my "Google Spreadsheet" (see previous post) to give a clear view of which scores of George Posca are "available". (Help appreciated!)
(I "found" some at Royal Library in Copenhagen). I have added my own "Am Strande"-score to the IMSLP-libray.
I felt it had its own "value" being the 1927 version from Benjamin's Leipzig "verlag" and with the added info/dedication on the front page "Meinem Freunde Emmo Ermrich". The added info did not solve any outstanding "issues" regarding Posca, however.
"Emmo Ermrich" is a complete anonymous person (to me).
