History

In 1830, the first permanent white settlers came to Northwest Indiana. The earliest historical records date back to 1838. On June 1, 1855, the original plat of the town was established. Aaron Norton Hart, a settler from Philadelphia, Pennsylvania, played a key role in developing Dyer’s infrastructure in the 1860s and 1870s. Hart supervised construction of roads and the implementation of a drainage ditch system, allowing agricultural and commercial use of the marshy land. Hart was killed in 1883 while working on a ditch near Plum Creek. Hart Street, one of Dyer’s major north–south streets, bears his name. Hart’s wife, Martha Dyer Hart, is the town’s namesake.

Dyer was incorporated as a town under Indiana law on February 8, 1910. Upon incorporation, Dyer was divided into three wards: The first ward consisted of all land within town limits lying west of Hart Street; the second ward comprised the section east of Hart Street and south of Lincoln Highway; the land north of Lincoln Highway and east of Hart Street formed the third ward.

Meyer’s Castle was listed in the National Register of Historic Places in 1984.
