Hymn Lyrics Search - Name That Hymn

I am in possession of a beautiful German hymn which is composed by the American composer Merritt J. Munger. I am certain it is out there as he is American, but I have just about given up searching. I cannot even locate the German version online. I was hoping that there is a teensy tiny chance that someone out there may know it, or at least give some clues about it. I can't be the only one that has ever heard it! I have attached a scan of the hymn.
