Yep, my great-grandfather was one of the most famous scientists/ constructors in Mongolia, famously dubbed ‘king of the ice’ for his contributions to provide improved food storage possibilities to the country, travelling every corner of it.
He grew up in a poor nomadic village before going to the capital and starting to study there somehow, a very impressive feat given that Mongolia in those days was so extremely poor and terrorized by Russia that that was usually a privilege reserved to the wealthy.
He earned a great fortune that all of his children managed to squander within a few years, but his anniversary is still being celebrated every year publicly to this day.
There are even biographies written about him, in the more recent ones a family photo where he holds me as a tiny baby in his arms.
