He's Austrian which is also known as "Germanic Race" he was coming from same family with Germans and people from Switzerland cause all of them are known as Germanics.
According to some myths some say he might had Jewish background aswell and Hungarian since Austria was united with Hungary before (Austro-Hungary Empire) As far as I know there are a lot of black haired people aswell living in Hungary.0
