The early influx and development of industry in Kearny dates back to 1875 when the Clark Thread Company of Paisley in Scotland extended its activities to the United States by erecting two large mills in Kearny, and adding two others in 1890.
These mills brought to Kearny thousands of Scots immigrants.
Many of them would play on Kearny's soccer teams in National Association Football League.
Many are buried at Arlington Memorial Park in the Kearny Uplands.

In 1876, the Mile End Thread Mills started operating, giving employment to several hundred operators.

In 1883, the Marshall Flax Spinning Company of England erected a large plant in Kearny, known as the Linen Thread Company.
Their need for experienced flax spinners brought an influx of workers from other sections of the British Isles.
Families of those early textile workers were the nucleus of Kearny's present population.

The Puraline Manufacturing Company, later called the Arlington Company, which became a subsidiary of E. I. DuPont de Nemours Company, had purchased a large tract of land east of the Arlington Station on the Erie Railroad extending well out, north of the railroad embankment, into the meadowland.

In 1887, Sir Michael Nairn established the Nairn Linoleum Company of Kirkcaldy in Scotland, now the Congoleum Nairn Company of Kearny, giving further impetus to local industrial growth.
This also led to the growth in the Scottish American population which in the 1960s was about 21,000, accounting for more than half of the town's residents.

In 1902, the Lovell–Dressel Company, manufacturers of marine and railway lamps and fixtures, located in Kearny adjacent to the Erie Railroad.

Other industries which located in Kearny include: Swift & Company, Koppers Company, Theobald Industries, Standard Tool & Manufacturing, Wilkata Box Company, Harris Steel Company and L & R Manufacturing.
 Between 1926 and 1986, the Kearny Works of Western Electric employed as many as 24,000 in producing a variety of hardware and supplies for the Bell System and was the home of the "Kearny Standard" for tools and equipment, and was sold by AT&T in 1984 by which time the plant had 4,000 employees who earned a total of $128 million a year, making it one of the county's largest employers.

Cargo ships were built at Kearny Yards during World War I, and warships during World War II.
