I heard this one listening to an interview with Peter Schreier on ZDF (YouTube, 2DF Da Capo, interviewed by August Everding):

"Nomen non est omen."
Karl Böhm (at a press conference in Prague, commenting on the name of the tenor Peter Schreier, i.e. Peter Screamer)

(transl.: The negation of nomen est omen, i.e. the name is a sign or the name speaks for itself.
So in this particular instance, a good translation could be by name, but not by nature.)
