History & History Related Items

Early industry in the area was logging when a sawmill and gristmill were opened in 1732. Two small hamlets were begun in the mid 1700’s – Sampton and Brooklyn. Outside of these two areas there was mostly small family farms. As the fight for independence grew, the area was involved in much activity from both sides of the war. General Washington moved his troops to an area now known as “Washington Rock” to flee the British army. The first post office opened in 1877 with the name of New Brooklyn. After about ten years, the name was changed to South Plainfield. The name was chosen because of the location being near to Plainfield which was an important area at the time. The railroad also came through South Plainfield for the same reason. Once the railroad came, more business, residences and people followed. Many historic homes, churches and businesses remain from this era, including the First Baptist Church of South Plainfield on Hamilton Blvd. The Volunteer Fire Department was created in 1907 and still exists today. By the early 1900’s, South Plainfield had grown quite a bit with many businesses, farms, school and even a movie theater. There was an airport built on the Hadley farm in 1924. Though used by private individuals, it was mainly built for the use of the postal service in the area.

South Plainfield was incorporated on 12 March 1926 with William Hamilton as the first Mayor. The following years included the Great Depression during which time the small town eked out an existence, surviving, but with not much growth. Finally, during the late 1930’s and early 40’s, prosperity began to sneak into the area with new employers who hired many local residents. By 1940 there was a population of about 5,300 people. During the 50’s many new housing developments sprang up and the town began to grow. The population was 8,000 in 1959 and 18,000 in 1960. By 1976, the population had grown to 23,000 residents. Since that time, the numbers have remained fairly stable.
