In 1917, when Fr. George Forst became the pastor at St. Paul Church he did everything he could to make St. Paul High School into a four-year licensed High School. Fr. Forst went to the Fisher Family who owned Fisher Body and asked them for help in the realization of his dream. The School was completed in 1921. It was the first Roman Catholic Four Year Licensed High School between Cleveland and Toledo. The school also boasted of containing one of the most sophisticated High School Chemistry Labs in the state at the time.
