Emil Kapaun's hometown of Pilsen, Kan. is a traditionally Bohemian/Czech community. While Kapaun's parents insisted on speaking English in their home, many Pilsen residents did not. During Emil's childhood, the pastor of St. John Nepomucene parish in Pilsen spoke Bohemian/Czech. When he would visit the local school and quiz students on their religion lessons, he questioned them in Bohemian/Czech. The young Emil Kapaun would have picked up some of the Bohemian tongue, but when he was studying to be a priest and upon his return to serve in his home parish in Pilsen, he took classes in Bohemian/Czech so that he could celebrate Mass in that tongue.
