Tyner was founded in 1855, when Samuel Miller deeded his property to Thomas Tyner. The city was platted along the future route of the Plymouth-Laporte railroad. The Tyner City post office was opened on September 11, 1856. A college was to be located in the town, but plans were abandoned after the opening of nearby Valparaiso University. A hospital was also planned, but never erected. Tyner became a successful village in Marshall County, and a popular stop between area towns. Mr. Tyner was a man of some stature in the 1800s; his brother, James, was Postmaster General under the Grant administration, and Thomas assisted in the moving of the Indiana state capital from Corydon to Indianapolis. Tyner City was briefly incorporated into a town in 1873 due to a dispute, but this was abolished less than ten years later, and it has remained a village since. Thomas Tyner died in 1880, at age 80, and is buried on a hill in the town cemetery. Tyner City dropped the "city" from its name in 1894. Tyner thrived until the Great Depression, when the economy, along with trains being replaced with other forms of travel and commerce, started the town's decline. Over the next 50 years, businesses and residents moved to larger cities, and the school corporation was consolidated with nearby Walkerton to form the John Glenn School Corporation in the late 1960s. By the 1980s, very little of the village remained.
