I don't know who it is but unless the Iron cross has a swastika in the center then the uniform is pre WWII. Also goggleing "Iron Cross" most WWII ones were issued with red black and white ribbon. WWI were just black and whirte ribbon. Looks like more of a WWI uniform, could be german or another european pre WWII country. To bad you don't have a close up of neck medal and eppelets.
