Before working in Sandusky, Mr. Offenhauer taught in the Mercer County School system, served as superintendent of Mendon School, and was principal of Mount Vernon High School. After leaving Sandusky City Schools, he became principal at Lima Central High School. In 1937, he became the second president of Bowling Green State University.
Sadly, Roy E. Offenhauer was killed in an automobile accident in December of 1938. (After his unexpected death, another former Sandusky educator, Frank J. Prout, was named President of Bowling Green State University, the third consecutive Sandusky Schools Superintendent to hold the position.) Offenhauer Towers, residence halls on the campus of B.G.S.U., are named in his honor.
