Although it is known that the Potowatomie Indians once lived in the Buffalo Grove area, the first recorded history begins with the German immigrants from the Alsace-Lorraine region who came to farm this land in the mid 1840s. Descendants of these early settlers remain in the area today. The present St. Mary's Catholic Church, the Village's most prominent landmark, was built by the families of these early settlers in 1899.
Throughout the early 1900s, Buffalo Grove was a dairy farming community supplying the Chicago area with fresh dairy products. Farmers took their milk to G.B. Weidner's cheese factory in Buffalo Grove or to the train station in Wheeling for the seven o'clock milk run to Chicago. Although the first concrete road (Dundee Road) was built around 1930, the residential development of the Village did not begin until the late 1950s. On March 7, 1958, the Village of Buffalo Grove, consisting of 42 homes and 164 people, was incorporated. From a population of 670 in 1960, Buffalo Grove has since grown to a current population of over 42,000.
The Village of Buffalo Grove is located 35 miles northwest of downtown Chicago and overlaps Cook and Lake Counties. Buffalo Grove's adjacent Cook County neighbors include the Villages of Arlington Heights and Wheeling. In Lake County, adjacent communities include Long Grove, Vernon Hills, Lincolnshire and Riverwoods.
Buffalo Grove has been one of the fastest growing communities in the Northwest suburbs since its incorporation in 1958 when, on March 27th, the first Village officials were elected. The Village's Comprehensive Plan projects that the Village will ultimately reach 7,202 acres, over 100 times its original size. The Plan also estimates an eventual population of approximately 48,000 residents. At its beginning in 1958, the Village had 164.
As it has throughout its history, the Village will continue to meet the challenges associated with growth through sound management and planning. Unlike many other suburban communities which exhibit the problems and characteristics of rapid urbanization, Buffalo Grove has retained the characteristics which attracted its earliest residents. It remains a community of tree lined streets and well maintained homes, of neighbors and neighborhoods. Buffalo Grove provides both the amenities of a country atmosphere and the convenient access to the cultural, entertainment, and business centers of Chicago. Buffalo Grove was included as one of "Fifty Fabulous Places to Raise Your Family" in a nationally published book by that title.
