I remember The Ridgewood Historical Society when it was called the Paramus Historical and Preservation Society. The Ridgewood Historical Society came into existence as a result of a name change in 1996. They operate the Schoolhouse Museum building, formerly one of the first public schools in Ridgewood. According to their website, their mission is to preserve the building, as well as maintain, interpret, and exhibit the collection of artifacts representing the history, culture, and lives of ordinary people from Ridgewood and the surrounding area from the period of Native America to the early 20th century in a consistently innovative way.
The Schoolhouse Museum is located at 650 E Glen Avenue in Ridgewood, NJ., directly across from Valleau Cemetery and adjacent to the Paramus Reformed Church.
