History and Tradition

In August 1871, the Northwestern Ohio Normal School officially opened its doors, with a central mission to train teachers in effective classroom instruction methods. Since that time, ONU has shaped some of the brightest scholars, scientists, philanthropists, businesspeople, health care professionals and performers – to name a few. Through wars, economic turmoil, social unrest and other unprecedented challenges, Northern has always remained Northern.

From Vision to Reality

Ohio Northern’s ambitious, pioneering attitude has been alive since the very beginning. The school started with a single person and a single idea. With the help of the community, Henry Solomon Lehr founded the Northwestern Ohio Normal School in 1871. When the college’s curriculum grew to include pharmacy, engineering, law and business programs, its name was changed to Ohio Normal University and, eventually, in 1903, Ohio Northern University.

There should be a school patterned to the needs of the common people, and it must recognize God in all its teachings."
