HistoryA character grade: shown, never part of Dyer’s overall grade.
Indiana towns list more on the Register than most of the country (a typical Indiana town has 7.9 per 10,000 residents, the U.S. 2.4), so Dyer’s 0.6 sits near the middle of its state (45% of Indiana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B+. The pre-1940 share (±2.1 points) is firm at this size. Two sources give 1838.

What stands out about Dyer’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
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.
