Historical Markers in Ogle County, Illinois

Grand Detour, Ogle County, Illinois



  Early French traders who traveled the Rock River
named the large bend southwest of this point, Grand Detour.
Winnebago and Potawatomi villages in the area made
it a prominent location for fur trading posts, and during
the 1820's the United States government granted licenses
to traders at the "Grand Detour on Rocky River."

  Permanent settlement at Grand Detour began after
Leonard Andrus traveled up the Rock River in 1834 in search
of a town site. Impressed by the natural beauty of the re-
gion and the power and transportation potential of the
river, Andrus claimed the land and in 1836 laid out a village.

  A year later John Deere, a Vermont blacksmith, settled in
Grand Detour. While working in his shop, Deere heard farmers
lament that the rich Illinois soil stuck to the wooden and iron
plows they had brought from the East. Deere tackled the prob-
lem and shaped a steel plow out of a discarded saw blade
from the Andrus sawmill. The soil slid smoothly off the high-
ly polished steel surface, and as the demand for his plows in-
creased, Deere began production using steel imported from
England and later from Pennsylvania. Hight freight costs for-
ced him to seek better transportation facilities, and in 1847 he
moved from Grand Detour to Moline, Illinois, on the Mississippi
River, where he began manufacturing plows in quantity.
  Since the Rock River was never developed for navigation and
the railroads bypassed the community, Grand Detour retains much
of its nineteenth century atmosphere.
