Blasius Kozenn was a Slovenian cartographer. He has occasionally been misidentified as Slovak.
Blasius Kozenn was born into a poor farming family in the village of Hotunje, not far from Ponikva. After attending elementary school in Ponikva, he attended the upper secondary school in Celje, where he was accepted through the efforts of his elementary school teacher. He continued his studies in Graz and Klagenfurt, where he studied theology. He was ordained a priest in 1845.
