Chaplain Kapaun Memorial High School was named after Chaplain Emil Kapaun, a priest of the Wichita Diocese who served and died in the Korean War. It opened in 1956 another site on east Central Ave (not the same as the present site), in east Wichita, and was operated by the Jesuits as a preparatory school for young men. Jesuits served at the school in various capacities until the early 1990s. Alumni of the initial Chaplain Kapaun school recall that under the basketball court's "floating floor" was a rifle range, where students - under supervision - practiced marksmanship with school-supplied .22 cal rifles, and that supported a school rifle team.
