While it was still Union Township, portions of territory were taken to form Rutherford (as of September 21, 1881), Boiling Springs Township (April 17, 1889; now known as East Rutherford) and North Arlington (March 11, 1896). On May 15, 1917, the area was reincorporated by an act of the New Jersey Legislature as the Township of Lyndhurst, based on the results of a referendum held one week earlier. The township is named for Lord Lyndhurst.Kingsland explosionOn January 11, 1917, a fire started in Building 30 of the Canadian Car and Foundry Company, in what is now Lyndhurst, in a plant that was producing munitions for sale to the United Kingdom and the Russian Empire during World War I. After a spill of flammable liquid started a fire in a building where shells were cleaned, about 500,000, three-inch (76 mm) explosive shells were discharged in about four hours, destroying the entire facility. It was said to have been a spectacle more magnificent than the explosion at Black Tom in Jersey City, New Jersey.
