History The community (formerly part of a larger town called Harlem) officially became incorporated under the name of Forest Park on April 17, 1907. For much of its history, Forest Park was known as a "Village of cemeteries", with more dead "residents" than living ones; some figures estimate the ratio at 30:1, dead to alive. Forest Park cemeteries include Altenheim, Forest Home Cemetery (incorporating the German Waldheim Cemetery), Jewish Waldheim (producer Mike Todd is buried in Beth Aaron there), Woodlawn (including Showmen's Rest), and Concordia. Forest Home Cemetery is home to the famous Haymarket Martyrs' Monument. From 1925 to 1931, Forest Park had a radio station with a variety of call letters. The station began in 1925 as WHT. It was known as WNBA, with its studios near Des Plaines and Roosevelt Road from 1927 to 1928. In 1929, the call letters changed again, this time to WSOA and again to WCHI in 1929. As WSOA, the radio station had 5,000 watts of power. It went off the air for good in 1931. The Naval Ordnance Station Forest Park (originally a Naval Ordnance Plant) operated from early in World War II until most of the plant was replaced by a mall in 1971, with some of the site used as a Naval Reserve center until 2007. The plant employed up to 6,500 workers and produced 19,000 torpedoes during World War II. In 2007, the town held a summer-long centennial celebration. Forest Park has also held two other centennial celebrations, one in 1956 for when the first settlers came and one in 1984 for the 100th anniversary of the creation of the town of Harlem.
