I'm sure you mean Florian GeyEr. Florian Geyr happens to be a distinguished attorney in Germany. Florian Geyer was a 16th-century or so knight who died in a hopeless cause, the kind of guy the Nazis named cavalry divisions for. Sort of a Bavarian Braveheart, if you will, although his end was more ignominious than the character's (and perhaps less ignominious than the actor's career).
Geyer's unit, the "Schwarzer Haufen," is usually translated as "the Black Company," and of course the SS called themselves the "Black Companies."
Interestingly enough, both Florians covered about the same stomping ground -- the areas of Bavaria, Franconia and Swabia that formed the homeland of National Socialism. But their battles take place in somewhat different milieus.
