La Grange Park.

Between 1845 and 1860 the land that would become La Grange Park was settled by farming families, including the Diekes, Myers, Robbs, Wesemanns, and Kemmans, who tilled their acreage on what is now the village. After the Chicago Fire of 1871, displaced families arrived along the Burlington rail corridor, liked the area, and stayed, and the original farmers sold off pieces of their land to the newcomers. Much of the credit for forming the village goes to Alphonse H. Kemman, who organized an incorporation effort, and on July 14, 1892, La Grange Park was incorporated with about 300 residents. One of the new village's first official acts was to prohibit liquor sales.

For its first 50 years La Grange Park remained a quiet residential village with only a handful of businesses, no parks, and a single school, and as late as the 1930s many streets still lacked signage. Things began to change around 1943, when the village moved to create a park district, allow light manufacturing along the Indiana Harbor Belt rail right-of-way, expand its police and fire departments, and establish a central shopping area. The village's population settled near 13,000 to 13,500 in the modern era, reaching 13,475 at the 2020 census.
