History
Arlington Heights lies mostly in the western part of Wheeling Township, with territory in adjacent Elk Grove and Palatine townships, in an area originally notable for the absence of groves and trees.
Indigenous settlements
The land that is now Arlington Heights was controlled by the Miami Confederacy (which contained the Illini and Kickapoo tribes) starting in the early 1680s. The Confederacy was driven from the area by the Iroquois and Meskwaki in the early 1700s.
The French-allied Potawatomi began to raid and take possession of Northern Illinois in the 1700s. In the late 1700s and early 1800s, the Potawatomi expanded southwards from their territory in Green Bay and westward from their holdings near Detroit, until they controlled in an L-shaped swath of territory from Green Bay to the Illinois River, and from the Mississippi River to the Maumee River.
Throughout the 1830s, the Potawatomi maintained a camp in modern-day Arlington Heights that was used for six weeks out of the year as the Potawatomi migrated from their summer encampments to their winter encampments.
In 1833, the Potawatomi signed the 1833 Treaty of Chicago with the United States Government. As a result of the Treaty, the United States was granted control of all land west of Lake Michigan and east of Lake Winnebago in exchange for a tract of land west of the Mississippi. The land that is now Arlington Heights was ceded to the U.S. in this treaty, which sparked mass white immigration to the Northern Illinois area. The U.S. Government purchased the land for about 15 cents per acre, and then resold it to white settlers for 1.25 dollars per acre.
The Potawatomi would occasionally return to their holdings in Northern Illinois to honor their buried ancestors, but these return visits ended as old villages and burial sites were destroyed by white settlers to make way for farming. Descendants of the Potawatomi who once inhabited the land that is now Arlington Heights currently live on a reservation in Mayetta, Kansas.
Establishment as West Wheeling and Dunton
Many prominent roads in the Arlington Heights area were built on top of Native American trails: Rand Road was built on top of a Native trail which passed by the property of Socrates Rand, who built a tavern near a crossing on the Des Plaines River. Arlington Heights Road was developed from a Native trail that ran from what was once called Naper Settlement (now Naperville) to what was once called Indian Creek (now Half Day).
Around the same time, a trading post was established in the Southwest corner of the township by Frederick T. Miner, the cabins established near Miner's trading post came to be known as West Wheeling. In 1837, Asa Dunton, a settler who built one of the first cabins in what was then known as Deer Grove, registered three land claims for himself and two sons in the land in the west of Wheeling Township.
In 1845, Asa's eldest son, William Dunton, married Almeda Wood and brought her to the house he built beside the Potawatomi trail which then became known as Dunton's Road (and is now known as Arlington Heights Road). West Wheeling then became known as Dunton. The town's name changed several times before it officially became known as Arlington Heights in 1874.
William Dunton persuaded the Illinois & Wisconsin Railroad company to build track through his property. In 1853, Dunton sold 16 acres of his land to the company for $350. The first Dunton train station was built in 1854. The construction of the railroad helped to expand the population of Dunton, as it was easier for settlers to reach the village.
By 1850, the area had largely changed its ethnic composition, as many German farmers from Saxony had arrived during the 1840s. John Klehm was a prominent German resident of Arlington Heights. Initially a potato farmer supplying the Chicago market, in 1856 he began a nursery for cherry, apple, and pear trees, later moving into spruce, maple, and elm, and then flowers. By the late 1850s the area had become noted for its truck farms, sending dairy products as well as vegetables to Chicago on the railroad.
Civil War era and after
Several Dunton residents served in the American Civil War, however only three of those residents who left for the war returned. One of the survivors, a recently naturalized Alsatian named Charles Sigwalt (namesake of Sigwalt Street), fought at the Battle of Chickamauga and the Battle of Kennesaw Mountain. Warren Kennicott (namesake of Kennicott Avenue) was killed in action at the Battle of Gettysburg.
During the 1860s, Arlington Heights was a stop for many Union soldiers travelling South to fight the Confederacy or traveling North to fight in the Dakota War of 1862. During and after the Civil War, the Chicago metropolitan area experienced a population boom. Dunton continued to slowly grow, in part because of an influx of German immigration. By the 1870s, Dunton's population had surpassed 1,200. By this time, the village had acquired a blacksmith, a cheese factory, a hardware store, and a hotel.
Balaam Lee was the first Black person to live in Dunton. He was a formerly enslaved man who followed a returning Union soldier from the Civil War to Dunton in the 1860s. He was born in the 1830s and died in 1894. In Dunton/Arlington Heights, he worked at Klehm's Nursery and also as a mule driver.
In 1874, Dunton's name was officially changed to Arlington Heights. In 1878, Civil War veteran Charles Sigwalt and his brother John founded the Sigwalt Sewing Machine Company, which made 40,000 machines from the period of 1878 to 1883. The company was destroyed by a fire in 1895.
Two of Arlington Heights' first Black residents were Fannie White (1856–1946), an artist, and her husband Frank White (1862–1953), a barber shop owner. They moved to Arlington Heights in 1888 and lived on Dunton Avenue until Fannie's death. In 1894, Arlington Heights' first fire department formed during the tenure of Mayor Charles Sigwalt. Frank White was a charter member of the fire department and he also was elected its first President. He was involved with the fire department for 40 years, serving as a historian.
Arlington Heights was an early commuter suburb. The town developed religious institutions that reflected the origins of its citizens. The first churches were Presbyterian (1855) and Methodist (1858), with St. Peter Lutheran Church, a German Lutheran church, following in 1860. Today, the village has many Roman Catholics, boasting three very large churches: St. James (founded 1902—now home to 4,600 registered families), St. Edna (2,800 registered families), and Our Lady of the Wayside (3,100 registered households). In addition, there are several Lutheran and evangelical churches, along with congregations that are members of the United Churches of Christ, Episcopal Church, and Christian Church (Disciples of Christ).
20th century to present
By the start of the 20th century, Arlington Heights had about 1,400 inhabitants. The village continued to grow slowly with the area primarily being farms and greenhouses until after World War II. By then Arlington Heights was also known for Arlington Park, a racetrack founded in 1927 by the California millionaire Harry D. "Curly" Brown upon land formerly consisting of 12 farms. Camp McDonald and two country clubs were founded in the 1930s. On July 31, 1985, a fire burned down the grandstand. A six-story grandstand was completed and opened for use June 28, 1989.
A population explosion took place in Arlington Heights in the 1950s and 1960s. The growth of automobile ownership, together with the expansion of the Chicago-area economy, the baby boom, and white flight from the city, drove the number of people in the suburb (geographically expanded by a series of annexations) up to 64,884 by 1970. By then virtually all the available land had been taken up by urban sprawl, and the formerly isolated depot stop found itself part of a continuous built-up area stretching from Lake Michigan to the Fox River.
Village of Arlington Heights v. Metropolitan Housing Development Corp., 429 U.S. 252 (1977), was a United States Supreme Court case about housing discrimination. The case involved an Arlington Heights zoning board decision denying a zoning variance to build a multi-family housing complex on property owned by the Clerics of St. Viator near Saint Viator High School. The Village argued that the zoning board blocked construction to "protect property values and the integrity of the Village's zoning plan," which only allowed single-family homes in the neighborhood. The developer argued that the intent and practical effect of preventing the development was to maintain racial segregation. The Court held that the ordinance was constitutional because there was no proof that "discriminatory purpose was a motivating factor in the Village's decision."
