Ignatius Mrak (16 October 1818 - January 2, 1901) was the second Roman Catholic Bishop of the Diocese of Marquette, in Michigan, United States.[1]
Mrak was born in the small Carniolan village of Hotovle in the Austrian Empire (now in Gorenja vas-Poljane, Slovenia). He studied theology in Ljubljana and then went to the diocesan seminary in the same town. On August 13, 1837 he was ordained priest by Bishop of Ljubljana Anton Aloys Wolf.
In 1845, he moved to the United States. He first stayed with his fellow Slovene bishop Francis Xavier Pierz in Michigan. In 1851 he moved to Minnesota, where he stayed until 1869, when he was appointed bishop of Marquette, following Frederic Baraga. Mrak died in Marquette in 1901.
