History
Marmion Academy was created in 1933 when the monks of St. Meinrad Abbey combined Jasper Academy (Jasper, Indiana) with the Fox Valley Catholic High School, which the Augustinians had just returned to the diocese of Rockford. During the Great Depression era it was difficult for students to pay their tuition, so the monks, in 1935, associated with the JROTC program and changed its name to Marmion Military Academy. In order to provide more options for its student body and a return to the original spirit of the school, the monks of Marmion Abbey decided to make JROTC an optional program and to reinstitue the original name of the school, Marmion Academy
