Cranford was incorporated as a township by an act of the New Jersey Legislature on March 14, 1871, from portions of the Townships of Clark, Linden, Springfield, Union and Westfield. Portions of the township were taken to form Garwood (in 1903) and Kenilworth (in 1907). The township’s name is said to derive from the Crane family,including John Crane, who built a mill in 1720 along the Rahway River

NJ Transit rail service is available at the Cranford station, along the Raritan Valley train line, with service to Newark Penn Station and to Penn Station in Midtown Manhattan via Midtown Direct. It is part of the New York City metropolitan area.

Historic figures

Though no known Cranford residents died in the American Civil War, at least 22 were active in the Union Army at the time of General Robert E. Lee’s surrender. Cranford’s last surviving Civil War veteran died in 1935.

James E. Warner is a former sheriff of Union County who was the namesake of the James E. Warner Plaza at the Cranford Train Station. Concerned by the then-growing pollution of the Rahway given the cleaner waters of his youth, Warner advocated for the preservation of the Rahway River and Rahway River Parkway parkland. One of Sheriff Warner’s successful targets in fighting Rahway River pollution was his battle against the discharge of paper makers; one such site is now the regional theater known as the Paper Mill Playhouse in Millburn. The Cranford Canoe Club, built in 1908, continues to offer canoes and kayaks for rent on the river in town.

Charles Hansel was co-founder of the Union County Parks Commission that preserved parkland all along the Rahway River and its tributaries in the 1920s, a greenway now known as the Rahway River Parkway.[35] He was an engineer for the Pennsylvania Railroad and Central Railroad of New Jersey. Hansel lived in the 300 block of North Union Avenue in a home that still stands today, later moving to what is now Gray’s Funeral Home, near what is now called Hansel’s Dam by Sperry Park. For his Rahway River preservation efforts, a memorial copper plaque was placed to Hansel in Echo Lake Park.
