Firstly he's a german prince born in mexico(thus competing as Mexico's only winter olympian since 1928), and at 55 he's the 2nd oldest winter olympian ever.
"Von Hohenlohe is a photographer. Here he is posing at one of his many gallery showings. At this particular 2005 show, titled "It's Me!", every photo featured von Hohenlohe." - deadspin
In addition he's related to the Agnelli family(founder of Fiat and owner of Juventus). Oh and to top it all off he's fluent in 5 languages.
There's a shitload more about him but I'm too lazy to copy more across, either way, he definitely deserves the title of most fascinating Olympian.
