He was apparently a former Ukrainian national who found himself in Krakow, Poland during World War 2... The NAZI's paid him to publish a newspaper for expat Ukrainian's encouraging them to join up with Nazi forces... You need a printing press for that, so they took a Jewish publisher in Krakow and and shipped him and his family to the gas chambers, and Chrystia's grandfather then moved into their house and took over their printing press so he could produce his pro-Nazi propaganda, and have a nice place to live.
And he was so inspiring to Chrystia as a child... She often referred to him in her narratives while running for office.
He certainly sounds like a 'real great' guy... Don't you think?
That picture reminds me of some Creature Feature horror caricature. Some humpback dude with the exact same face. YIKES!!
