Des Plaines, Illinois

Potawatomi, Ottawa, and Ojibwe (Chippewa) Native American tribes inhabited the Des Plaines River Valley prior to Europeans’ arrival. When French explorers and missionaries arrived in the 1600s in what was then the Illinois Country of New France, they named the waterway La Rivière des Plaines (English translation: “River of the Plane Tree”) as they felt that trees on the river resembled the European plane trees. The first white settlers came from the eastern United States in 1833, after the Treaty of Chicago, followed by many German immigrants during the 1840s and ’50s. In the 1850s, the land in this area was purchased by the Illinois and Wisconsin Land Company along a railroad line planned between Chicago and Janesville, Wisconsin. In 1852, the developers built a steam-powered mill next to the river to cut local trees into railroad ties. Socrates Rand then bought the mill and converted it into a grist mill, which attracted local farmers. The Illinois and Wisconsin Railroad made its first stop in the area in the fall of 1854.

In 1857, the Chicago, St. Paul, and Fond du Lac Railroad began running its route, stopping[citation needed] near the mill on the Des Plaines river, where a small business section had grown up. The railroad platted the prospective town of Rand at the site. In 1859, the Chicago and North Western Railway purchased the rail line, giving the train station the name “Des Plaines”. In 1869, the Rand subdivision’s name was changed to Des Plaines, and the village of Des Plaines was then incorporated.

Des Plaines was reincorporated in 1873 and elected a village board the following year. Local brick manufacturer Franklin Whitcomb served as the first Village President.

In 1925, village residents voted to convert to a city form of government and annexed the village of Riverview to the south. Subsequent annexations included the Orchard Place area in 1956. The city experienced rapid growth after World War II and with the opening of nearby Chicago-O’Hare International Airport.[citation needed]

Des Plaines was the site of Ray Kroc’s first McDonald’s franchise, which opened in 1955. The restaurant was demolished in 1984, and a replica was built on the site as a museum dedicated to McDonald’s history. In 2017, McDonald’s announced plans to demolish the building due to repeated flooding. The building has since been demolished.
