The Janesville High School building (later the Jefferson school) was finished, and the high school classes were transferred from the old academy, with Levi Cass as principal.

The evidence

• “In May, 1859, the High School building (now the Jefferson school) was finished and the high school classes were transferred from the old academy to the new building. This was considered the ne plus ultra of school buildings at the time, and it still remains a sightly landmark; standing on the highest elevation of the city, with its three stories and large cupola, it is the first object seen when driving into Janesville from any direction.”
