Nathan Marcus Adler

Even though he was born in Germany, Rav Adler became the Chief Rabbi of the British Empire.  Unlike his Western European bretheren, he wore a fancy "wheel cap" style hat, similar to those worn in Southeastern Europe.  But I suspect this has more to do with the British prediliction for fancy hats.
