At the onset of this project 2 years ago now, one goal was to disambiguate this Ernst Collin from "the other" Ernst Collin. This was described in The Story of Two Ernsts on this blog. There I mentioned that:
To become more independent he moved to Great Britain to teach at the Berlitz School, spent some time teaching for Berlitz in Constantinople, and returned to Germany to fight in WWI.Digital collections have been an amazing resource for this project, one of the newer useful ones being European Library and ZEFYS: Zeitungsinformationssystem of the Staatsbibliothek zu Berlin. Both are useful because the search results of the European Library provide for full-text searching and link to the paper with search results highlighted. ZEFYS, the actual home for these papers is harder to use, but allows for PDF download of the that page or the whole issue which the European Library does not. Among recent newspapers added were the Berliner Tageblatt and Berliner Börsenzeitung, two daily newspapers. Searching for Ernst Collin, Georg Collin, Wilhelm Collin, what appeared but this in the on page 48 of the 31.01.1909 edition of the Berliner Tageblatt.

Here we have "the other" Ernst giving a keynote lecture on the differences between the old and new Esperanto in Berlin for a 12 hour workshop.
