What drives Kiel’s History grade

HistoryA character grade: shown, never part of Kiel’s overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Kiel’s 10.1 sits above most of its state (77% of Wisconsin towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B to A. The pre-1940 share is a Census survey estimate (±7.2 points). The founding year is the first post office, not a stated founding date.

What stands out about Kiel’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1852 Charley Lindemann immigrated to the area and began a settlement among the Native American Menominee and Potawatomi tribes. His wife named the community after her home town of Kiel, Germany. Two years later, Col. Henry F. Belitz, later nicknamed the "Father of Kiel", built a hotel and mill along the north side of the Sheboygan River. A road was built across Wisconsin to connect Green Bay with Milwaukee area communities. The bridge was built across the Sheboygan River in 1858 connecting Kiel with Sheboygan. In the late nineteenth century to the early twentieth century, Kiel became a manufacturing area with businesses specializing in brick, wood shoes, machine, and furniture manufacturing.
The Kiel post office opened in 1861, the earliest record of the town by name (U.S. post office records).
