Incorporated as a Borough in 1853, Hackettstown was re-incorporated as the Town of Hackettstown by special Charter in 1970.
By 1886 Hackettstown had 2,800 inhabitants within its area of approximately 2-1/2 square miles. It received its name from a gentleman by the name of Samuel Hackett, at the time of the raising of the frame of the first hotel on the site of the Warren House. This was most probably in the year 1764. Few places in the county of Warren have such a beautiful natural location as this thriving town. From the summit of Bucks Hill, a rocky height half a mile from town, the town and adjacent country can be seen to the best advantage. Towards the south the fertile valley of the Musconetcong stretches as far as the eye can reach.
It is said that Samuel Hackett was the first settler of this town, and that he settled there about the year 1720. His father-in-law had received large grants of land from the King of England, and he in turn gave 10,000 acres to Mr. Hackett.
He once lived in a log house that stood on the eastern bank of Bowers foundry pond. Thomas Shields, Jr., a few years ago [1880s] removed the Lozear house, which it is said was his last residence. He was one of the judges of Morris County before Sussex and Warren were taken in from it.
