What drives Oshkosh’s History grade
On its age, its old homes and the National Register, Oshkosh is more historic than 95% of U.S. towns, #12 of 362 in Wisconsin. All 3 inputs are above most U.S. towns; its National Register listings ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Oshkosh’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 Oshkosh’s 67.0 sits above most of its state (91% of Wisconsin towns have fewer) while its 447 historic buildings outnumber those of 97% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share (±1.6 points) is firm at this size. Two sources give 1818.

What stands out about Oshkosh’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Oshkosh was named for Menominee Chief Oshkosh, whose name meant "claw" (cf. Ojibwe oshkanzh, "the claw"). Although the fur trade attracted the first European settlers to the area as early as 1818, it never became a major player in the fur trade. The 1820s mining boom in southwest Wisconsin along with the opening of the Erie Canal shifted commercial activity away from the Fox River Valley and Green Bay. Soon after 1830, much of the trade moved west, as there had been over-trapping in the region.
