herbeck von herbeck hi james well i think there are three separate questions the two articles i merged were most definitely about the same person unless people with virtually the same name the same nationality working in the same field shared exactly the same day of birth and exactly the same day of death technically possible but extraordinarily unlikely i would suggest now there may indeed have been another johann herbeck who worked around that time but i'm no expert and i've never heard of such person as to why the bruckner biographies have him as herbeck and not von herbeck it's probably because he got his von only in three years before his death for the great bulk of his life he was simply herr herbeck so it's appropriate to refer to him that way in a biog of another person for an encyclopedia article however he gets his full final name this is a very handy source for some further updates to the article cheers
