In 1900, Levi Prosser, the son of a prominent Bloomfield family, left 1/6th of his estate ($16,255.85) to the Town of Bloomfield to establish a free public library, although Levi Prosser himself was a resident of Massachusetts. Prosser Public Library was dedicated in 1903 and was housed in a multi-purpose building that included the Town Hall and was located on the Library’s present site, 1 Tunxis Ave. The library started out as one room in Town Hall, but eventually expanded to the entire first floor of the building.

In 1963, the original building was torn down. Unfortunately, while the library’s collections were in storage at the Center Grammar School on Jerome Ave, that building was destroyed by fire along with most of the collections. The present Prosser Public Library building was completed and dedicated in 1965.
