Deletion of Alexander Berghaus

Comment: I'm not especially impressed by his citation counts, but as a member of the Academy of Sciences Leopoldina http://www.leopoldina.org/de/mitglieder/mitgliederverzeichnis/member/828/ he clearly passes #C3. And works such as https://books.google.com/books?id=yXnSXJAkeNsC&pg=PR7&lpg=PR7 this (a biography of him as a contributor to a book, but written by the editor of the book) appear to meet the need for reliable secondary coverage of him
