Pontiac is a city in and the county seat of Livingston County, Illinois, United States. The population was 11,150 in the 2020 Census. The 1984 movie "Grandview, U.S.A." was set in Pontiac.
Geography.
Location.
According to the 2010 Census, Pontiac has a total area of , of which (or 98.22%) is land and (or 1.78%) is water.
Most of the land adjacent to Pontiac is farmland.
Pontiac lies on the Vermilion River. On December 4, 1982, Pontiac had the worst flood in the town's history, cresting at 19.16 feet, caused by a major storm. The most recent flooding occurred on January 9, 2008, cresting at 18.85 feet, the second worst in the town's history.
History.
Slow beginnings.
Pontiac was laid out on July 27, 1837, by Henry Weed and brothers Lucius Young and Seth M. Young. A small group of people gathered at the cabin of Andrew McMillan on the banks of the Vermilion River. They intended to create a county seat for the newly established county of Livingston. The town they would design was nearly the last of hundreds of new towns laid out in Illinois between 1835 and 1837. Livingston County, created five months before, had almost no functioning government. Illinois, like the rest of the nation, was slipping into an economic depression that would cause the next decade to be called “the hungry forties". 
Moreover, the men had guaranteed a great deal in order to be granted the right to found the seat of the new county. They had agreed to donate twenty acres of land for a courthouse, another acre for a jail, and a pen for stray livestock. They had agreed to give the new county $3,000 toward erecting new buildings, to erect “a good and substantial wagon bridge" across the Vermilion River, and to build a county courthouse. None had the ready cash to support such an effort. They had simply promised to do so, and their promises were guaranteed by three others: C. H. Perry, the county's first storekeeper; James McKee, who had an interest at a mill at the new town site; and Jesse W. Fell, an Illinois legislator and Bloomington land dealer. Fell was the person who had been responsible for creating the new county. As it turned out, for the town's three founders, the future of Pontiac would not be their problem. Within five weeks of the founding of the town, both Young brothers would be dead, and Henry Weed soon drifted away and would die of pneumonia in 1842 while working on a railroad near Binghamton, New York. The men who founded Pontiac would not be its developers.
The design of Pontiac.
The design of the original town was typical of Midwestern town plats in the 1830s. Since there were neither improved roads nor railroads, the plan was centered on a town square; such squares would become much less common after the arrival of railroads. In these early towns, the public square served to define the town center and therefore to establish the location of the highest value lots. Isaac Wicher, the County Surveyor, made the initial survey of Pontiac and staked out its streets and lots. Pontiac was the only town laid out in Livingston County in the 1830s, but similar square-centered towns from that time can be found at Metamora, Lexington, Danvers, Clinton, and Le Roy, all established within two years of Pontiac. The original Town of Pontiac differed somewhat from these others because it was unusually large, with ninety-three blocks, most divided into eight lots with some left unsubdivided. The new town extended on both sides of the river. The square, where the courthouse would be built, was bounded by Washington, Madison, Main and Mill Streets. At first, lots were sold for as little as five dollars each and, even as late as 1850, good lots could be had for as little as twenty dollars each.
Naming and first attempt to take away the county seat.
Jesse W. Fell had been asked to use his influence to establish a post office in the area. In order to do this, he needed a name and selected “Pontiac” in honor of the Native American leader, who as far anyone knew had never set foot in the area that would be Livingston County. Fell had also selected the name of Livingston County. The town did have a few advantages. It was a good place to cross the river, there was a good mill seat, and James McKee was working to establish a sawmill on the Vermilion river at the town site. By 1838, the mill was in operation. Before leaving the county, Seth Weed had built the first house in Pontiac.
After the Young brothers' deaths, Isaac Fellows came west to settle their estate. He liked the location and took up residence. Work started on the courthouse, but was behind schedule. Early growth was so slow that rivals decided there was a good chance they could strip the honor and the business of the county seat from Pontiac. In 1839 they forced the matter to a vote. The proprietors of Pontiac, they argued, had not lived up to their obligations: the courthouse was unfinished and no bridge across the Vermilion had been built. Their new suggestion for the seat of Government of Livingston County, four or five miles upstream would, they said, be more centrally located. They complained that the site of Pontiac had been poorly chosen and was low, damp, and generally unhealthy. The people of the county agreed. By a margin of 81 to 56, they voted to move the county seat but a two-thirds majority was needed to relocate a county seat. As a two-thirds majority failed by a small margin, Pontiac was continued to be the location of the county offices. After considerable delay, the first Courthouse, a twenty-two by thirty-foot wooden building, was finished and, in 1847, the promised bridge across the Vermilion was completed. Shortly after the $450 bridge was opened, a sudden rise in the Vermilion river swept it away.
Second attempt to displace Pontiac.
The 1878 History of Livingston County remarked, “the town of Pontiac was little more than a name.” In the early 1840s it had only a half-dozen cabins and an unfinished courthouse, and everything was so scattered among “clumps of bushes” that the town was almost invisible. In 1848, August Fellows, who now owned much of the town, had managed to set up a hostelry. Some of the first church services in Pontiac were held at the tavern. In 1849 cholera swept through Pontiac, killing Fellows and two of his children. One early settler remembered that in Livingston County one person in two suffered from the disease. Fellow's widow, Maria Tracey Fellows, continued to run the hotel; she remarried Nelson Buck in 1850 and renamed the place Buck Hotel.
In 1851, there was a second attempt to displace Pontiac. On June 23, 1851, a town called Richmond was platted two miles east of Pontiac. Its backers included powerful local business and political figures. These men had calculated that the new Chicago and Mississippi Railroad would miss Pontiac and cross the Vermilion River at their location. Stores, shops, and a schoolhouse were built at Richmond. However, the Richmond speculators had not reckoned with Jesse W. Fell, who had retained a strong economic and social interest in Pontiac and had important friends among the railroad officials. The tracks missed Richmond and passed through Pontiac, with the station located in Fell's First Addition to the town. Richmond was quickly abandoned; some of its buildings were moved to Pontiac. On July 4, 1854, an exhibition train steamed into Pontiac, and a few months later regular service on the railroad, soon to be known as the Chicago and Alton, began.
Years of rapid growth.
Pontiac became a boom town. People flooded in and money for improvements was available. In 1856, Pontiac was incorporated. By 1866, the people of Livingston County could afford to spend $18,000 to construct a new stone jail in Pontiac. In 1870, the state established the Reform School at Pontiac. It was to be a model correctional institution for boys. Jesse W. Fell donated sixty-four acres, valued at $10,000, and more land was purchased. Livingston County issued $50,000 in bonds. The town of Pontiac added another $25,000 in bonds, and the first buildings were constructed. In 1892, this facility became the Illinois State Reformatory and is now the Pontiac Correctional Center.
In 1870, a fire destroyed $50,000 worth of buildings in downtown Pontiac and, like many Illinois towns, the town fathers, spurred on by insurance companies, created a “fire district,” a zone in the commercial part of the city where buildings had to be constructed of brick or some other fireproof material. These districts make Pontiac a classic example of one of the key visual features of the American Midwest: towns with brick commercial districts surrounded by wooden residences. Rebuilding was rapid, and growth continued. In 1871, The Chicago and Paducah Railroad was built with the aid of local bonds. The new railroad had revenues of $21,600 by 1877, while the older Chicago and Alton Railroad was handling $61,578 worth of goods. A second and larger courthouse was built. During Independence Day celebrations on July 4, 1874, stray fireworks started a blaze which burned the courthouse, the Union Block, and the Phoenix Block. Undaunted, Livingston County set out to find the best possible architect to design a new and more splendid building. They settled on John C. Cochrane, known for his work on the Capitol building in Springfield and for the Richland County courthouse. The building was finished in 1875 and was placed on the National Register of Historic Places in 1986.
Continued growth.
By 1880, improvements continued at a rapid pace, which included the installation of the first electric lights in 1882. In 1891, the wooden bridge over the Vermilion river was replaced by an iron span. Pontiac built a municipal water works in 1892. Between 1875 and 1900, new buildings were erected around the courthouse square.
Abraham Lincoln visited Pontiac in the 1840s and again in February 1855, when his train was snowbound on the nearby tracks, and he was taken by sled to spend the night at the home of Mr. John McGregor. On January 25, 1860, Lincoln was again in town when he addressed the Young Men's Literary Association. In 1858, Stephen A. Douglas and Owen Lovejoy, the abolitionist, both visited Pontiac. When local people learned in 1880 that former president Ulysses S. Grant would pass through Pontiac on his way to visit his son, they begged the general to stay over for breakfast, and a large reception committee quickly arranged a celebration. William Jennings Bryan came to Pontiac on October 27, 1896 and returned on several other occasions. On June 3, 1903, during his whistle stop tour through Central Illinois, Theodore Roosevelt spoke in Pontiac and unveiled the soldier's monument. He spoke there again in 1910.
Automobile age.
In the American Midwest, new highways often parallel early railroads. This happened at Pontiac. The Chicago Mississippi, linking St. Louis with Chicago, was Pontiac's first railroad. In 1922 and 1923, Route 4, the first paved highway between Chicago and St. Louis, followed almost exactly the same route as the railroad. Local people called it the ‘hard road.” The new state highway passed along Ladd Street and brought traffic through the center of Pontiac. The 1891 iron truss bridge over the Vermilion proved inadequate to carry increased traffic over the river, and in 1925 it was replaced with a steel and concrete structure. Also in 1925, the designation of the road was changed to Route 66, but this was only a change in name, as most of this famous highway simply borrowed the pavement of Route 4.
The Threshermen's Reunion started in a modest way in 1949 at Pontiac's Chautauqua Park next to the Vermilion River as a gathering of interested people who brought together a collection of old farm machinery. The assemblage of steam engines and the people who ran them grew in popularity. In 1999, the sponsors purchased their own forty acres north of town.
The first phase of construction on Interstate 55 was finished in 1966, and in the early 1970s the road, which closely followed Route 66, was brought up to improved federal standards. Highway-oriented businesses soon clustered around these roads, at first on the north and south
