General Information about the Ohio State Reformatory

The Ohio State Reformatory, date unknown


In 1884 the Ohio state legislature approved the creation of a prison to serve as an intermediate step between the Boys' Industrial School in Lancaster and the Ohio Penitentiary in Columbus. The city of Mansfield was selected and land was purchased. Designed by architect Levi T. Scofield, the Ohio State Reformatory opened its doors in 1896 as a facility to rehabilitate young male offenders through hard work and education. A self-sufficient institution with its own power plant and working farm, the Reformatory produced goods in its workshops for other state institutions and provided opportunities for inmates to learn trades. It became a maximum-security facility in 1946, housing all types of offenders. Considered substandard by the 1970s, the Ohio State Reformatory closed in 1990.



We hold the following Ohio State Reformatory admission records and photographs of inmates:

Historical conduct record (admissions) 1896-1968 [State Archives Series 1706]


There are gaps in the collection and inmates for which we hold no admission records. In those cases,  you can learn basic information (name, serial #, date committed, age, color, offense, court in which convicted, maximum sentence, and possibly, date of release) from the index entry.

Each record contains serial number, name, date received, county of conviction, crime, minimum and maximum sentences, birthplace, birth date, and age, names of next-of-kin, family history,criminal history, physical description, parole information.



Bertillon cards with photographs 1901-1921 [State Archives Series 1416 AV]


There are gaps in the collection and there is not a card with photograph of every inmate.

Each card has two photographs of the prisoner: a profile picture and a face-on picture. Each card also gives the prisoner's name, any aliases used, race, county of conviction, crime, date of arrival at the Reformatory, occupation, nationality, any previous criminal record, age, year of birth, birthplace, and physical description.

The Bertillon system of identification of criminals was based on the measurement of certain bony lengths of the body and was used before fingerprints. It was invented by French anthropologist Alphonse Bertillon, and was adopted by the Ohio Penitentiary in 1887.
