Deletion of Engelbert Sonneborn

Comment: The w:de:Engelbert Sonneborn|page on the German Wikipedia has more about him, as well as more w:de:Engelbert Sonneborn#Einzelnachweise|more references.

I don't speak German, but he seems to have significant coverage, and therefore passes the |general notability guideline
