The town was named for LutheranministerJohn Christopher Hartwick, an early landowner of the town. He bought the area that now constitutes the township from the Mohawk Indians in 1763. Discontented with the sparsely settled communities of Palatine Germans in the Mohawk Valley to the north, which Hartwick believed made people immoral, he bought the original Hartwick Patent with the intent to build a "New Jerusalem". Hartwick tried to control development, stipulating that residents look to him as their religious superior. By the 1790s the shrewd land speculatorWilliam Cooper had sold most of Hartwick's land against his wishes. Instead of a New Jerusalem, Hartwick requested in his will that a Lutheran seminary be opened with his estate. Upon Hartwick's death in 1797, efforts to do this started but were complicated by the fact that Hartwick left his estate to Jesus Christ. The Lutheran seminary established at Hartwick in 1797 was incorporated in 1816. It moved to Oneonta after 1931 and in 1947 merged with the Hartwick College, established in 1927. The town was established in 1802 from the Town of Otsego. In 1803, the north town line was altered. The largest commercial enterprise to occur in Hartwick was probably the Southern New York Railroad which was constructed to the town in 1901. It was supported by extensive shops, a car barn and yards on the southeast side of the village. Many of the hamlets and crossings still show architectural signs related to the trolley line nearly a century after the last passenger service. The Hartwick Historic District, Mathewson–Bice Farmhouse and Mathewson Family Cemetery, Old Hartwick Village Cemetery, and The White House are listed on the National Register of Historic Places.
