You mean Otto von Bismark?
No, Hapsburg - the guy who should have been the ruler of the Austro-Hungarian empire if things had gone a little differently.
The site I"m looking for didn't pop up near the top on Google (I'll try to remember to look for a better reference tomorrow) but this site hints at it: " Well after the end of the Second World War, Otto von Habsburg finally renounced all claims to the Austrian throne (1961) and was eventually allowed to return to his home country in 1966. An early advocate of a unified Europe, he served from 1979 till 1999 as a Member of the European Parliament for the conservative German CSU party.
