History

First settled by the Lenape Native Americans, who called the area around Perth Amboy by the name "Ompoge" (meaning "level ground"), the settlement ultimately became a key port for commerce between Lower New York Bay and Philadelphia, connected first by stagecoach and eventually by railroad. The city was initially founded as a village by Dutch fishermen known as Radford's Ferry, but later become a key city to safeguard New Amsterdam from the British. When settled by Europeans in 1684, the city was named New Perth in honor of James Drummond, Earl of Perth, one of the associates of a company of Scottish proprietaries. The Algonquian language name was corrupted to Ambo, or Point Amboy, and eventually a combination of the native and colonial names was used. South Amboy is mentioned during the Revolutionary War in letters to and from George Washington referring to an "officer stationed on the South Amboy shore" and by General Washington himself writing that he was "now in Jersey" and suggesting the enemy "may proceed to South Amboy". Once known as Radford's Ferry, as well as the South Ward of Perth Amboy, South Amboy became one of the earliest townships around 1685 as well as one of the largest at 18 miles long and six miles wide.

In 1890, a huge fire destroyed an entire city block of wooden houses on the east side of Broadway, which led to the establishment of the city's first fire station that same year.

Ammunition explosions

As a result of South Amboy's strategic location as a transportation hub, the city has been heavily damaged by military explosives in two major incidents. The 1918 explosions occurred during World War I at the Gillespie Shell Loading Plant, just south of the town. The 1950 explosion struck as Healing Lighterage Company dockworkers were transferring ammunition from a freight train onto barges. Both disasters killed dozens and injured hundreds of local victims, damaged hundreds of South Amboy buildings, required emergency declarations of martial law, and scattered wide areas of ammunition remnants that continue to surface occasionally.
