Quincy (// KWIN-see), known as Illinois's "Gem City," is a city in and the county seat of Adams County, Illinois, United States, located on the Mississippi River. The 2010 census counted a population of 40,633 in the city itself, up from 40,366 in 2000. As of July 1, 2015, the Quincy Micro Area had an estimated population of 77,220.
During the 19th century, Quincy was a thriving transportation center as riverboats and rail service linked the city to many destinations west and along the river. It was Illinois' second-largest city, surpassing Peoria in 1870. The city has several historic districts, including the Downtown Quincy Historic District and the South Side German Historic District, which display the architecture of Quincy's many German immigrants from the late 19th century.
Quincy's location along the Mississippi River has attracted settlers for centuries. The first known inhabitants to the region were of the Illiniwek tribe. Years later, following numerous incursions, the Sauk, Fox and Kickapoo also called the site home.
The French became the first European presence to colonize the region, after Louis Jolliet, Jacques Marquette and the La Salle Expeditions explored the Upper Mississippi River Valley. Fur goods became a valuable commodity of the region, and European explorers and merchants alike were attracted to the prospects of the growing fur trade of the North American frontier. The Mississippi River, acting as a superhighway for transporting goods downstream, became the area's most vital transportation asset.
Following the events of the Seven Years' War, which ended in 1763, Great Britain took control of New France, including that of the Illinois Territory. The Illinois Territory changed hands again a few decades later during the American Revolutionary War.
After the War of 1812, the American government granted military tracts to veterans as a means to help populate the West. Peter Flinn, having acquired the land from veteran Mark McGowan for his military service in 1819, ended up selling 160 acres (0.65 km2) of land acquisitions to Moravia, New York native John Wood for $60. John Wood later founded Quincy, which at the time was coined Bluffs, Illinois.
In 1825, Bluffs renamed their community Quincy and became the seat of government for Adams County, both named after newly elected President John Quincy Adams. In addition, they originally named the town square John Square until eventually changing it to Washington Square. Quincy incorporated as a city in 1840.
In 1838, following the signing of Missouri Executive Order 44, many members of the Church of Jesus Christ of Latter-day Saints fled persecution in Missouri and found shelter in Quincy. Despite being vastly outnumbered by Mormon refugees, residents provided food and lodging for the displaced people. Joseph Smith then led members of the Church of Jesus Christ of Latter-day Saints 40 miles (64 km) upstream to Nauvoo, Illinois, in hopes of finding a permanent home. Also in 1838, Quincy sheltered the Pottawatomie tribe as they were forcibly relocated from Indiana to Kansas.
The 1850s and 1860s brought increased prosperity to Quincy. Steamboats and railroads began linking Quincy to places west, making the city a frequent destination for migrants. The founding of the Chicago, Burlington and Quincy Railroad in 1855, and the construction of the Quincy Rail Bridge, were major drivers for creating a transportation hub in the region to further commerce. It is during this time that the city's population grew enormously, from just under 7,000 residents in 1850 to 24,000 by 1870, helping Quincy surpass Peoria in becoming the second-largest city in the state (at that time).
One famous former resident of Quincy is George E. Pickett. The future Confederate general as a young man came to Quincy to live, and learn the law, from his uncle Alexander Johnson in the 1840s. Johnson was acquainted with Abraham Lincoln, and Pickett and Lincoln may have even met each other in Quincy.
In 1860, Quincy founder and Lieutenant Governor John Wood inherited the governorship after William H. Bissell died while in office. At the time, he was overseeing business interests and the construction of his mansion. The Illinois legislature allowed him to stay in Quincy during his tenure, effectively making Quincy a "second" capitol for the state. His absence from the official Governor's office in Springfield provided Abraham Lincoln a space for planning his Presidential run.
The matter of slavery was a major religious and social issue in Quincy's early years. The Illinois city's location, separated only by the Mississippi River from the slave state of Missouri, which was a hotbed of political controversy on the issue, made Quincy itself a hotbed of political controversy on slavery. Dr. Richard Eells, who was a staunch abolitionist, built his home in Quincy in 1835 and sheltered runaway slaves on their way to Chicago. His home became a major stop on the Underground Railroad. The divide over slavery climaxed in 1858, when Quincy hosted the sixth Senatorial debate by U.S. Senator Stephen A. Douglas and his challenger, Abraham Lincoln. With an estimated crowd of 12,000 in attendance, Quincy was the largest community at which Lincoln and Douglas debated.
Lincoln and Douglas again confronted each other in the 1860 Presidential election and the resulting campaign again divided Quincy and the surrounding region. Lincoln enthusiasts and Quincy's chapter of the Republican Party's para-military organization Wide Awakes, while en route to a political rally in Plainville, marched upon nearby Payson, which was a community predominantly filled with Douglas supporters. Although a confrontation was avoided while en route to Plainville, Douglas supporters shot upon the Wide Awakes on their journey back to Quincy, resulting in a skirmish known as the Stone Prairie Riots.
The Civil War brought increasing prosperity to Quincy. Although the battles took place far from the city, Quincy was the organization site for several Illinois volunteer infantry regiments, including the 16th, 50th, 78th, 84th, 137th, 138th, and 151st. Following the Reconstruction Era, Quincy was selected as the location for Illinois' first Veteran's Home in 1886.
Immigration to Quincy
Early immigrants to Quincy came predominately from New England, seeking better land. They brought with them progressive values, such as public education and abolitionism. Starting in the 1840s, migrants from Germany settled in Quincy to escape revolutions among the German provinces and conflicts between the European powers. German migrants mainly lived in close proximity to one another and settled predominantly in the southern parts of the city, influencing much of Quincy's historic architecture and creating the South Side German Historic District. Collectively, the south side of Quincy became known as Calftown, due to the fact that nearly every household possessed a cow. Among the notable German-Americans from Quincy's Southside was Louise Maertz (1837-1918), a nurse during the American Civil War.
20th and 21st centuries
Throughout the 19th century, Quincy had grown from a backwater hamlet along the Mississippi River to become one of the state's most important cities and ports. Activity from rail and steamboat continued to flourish and Quincy benefited from the increased traffic. It was during the early decades of the 20th century that many of the city's historic buildings in the Downtown Quincy Historic District were constructed, including the city's first skyscraper, the Western Catholic Union Building, in 1925.
The automobile and its surging popularity pushed Quincy to consider alternatives to Mississippi River crossings. Prior to the automobile, the most popular means of crossing the near-mile wide river was by boat or ferry. The need for a bridge was apparent. In 1928, construction began on the Memorial Bridge which was a two-lane truss toll bridge; it opened in May 1930. By 1945, the city had repaid its outstanding bonds and eliminated the toll.
On April 12, 1945, a tornado ripped through the business district of Quincy and severely damaged the courthouse. The wind was so severe that it blew the roof off the structure, damaging it beyond repair. Because the incident occurred a few hours after news reached Quincy of President Roosevelt's death, several residents joked that "FDR and God were just fighting over the power up there." Five years passed before a new courthouse was completed.
In 1987, the cable-stayed Bayview Bridge was constructed to help alleviate traffic on the aging Memorial Bridge. Today, both bridges complement each other by carrying westbound (Bayview) and eastbound (Memorial) traffic. Although lighting was originally intended for the Bayview Bridge during its construction phase, the actual installation of lights didn't occur until 2015.
During the Mississippi River flood of 1993, riverside businesses and industries suffered extensive damage when the river crested at a record 32.2 feet (9.81 m), 15 feet (4.6 m) above flood stage. For a time, the Bayview Bridge, one of Quincy's two bridges, was the only bridge open across the Mississippi River between Alton, Illinois and Burlington, Iowa. The Memorial Bridge was closed from the end of June, due to water over its western approach. On July 16, 1993, the Bayview Bridge closed when the river submerged the land on the west side of the Mississippi River at Taylor, Missouri; Quincy's bridges reopened 73 days later on September 26, 1993.
On November 19, 1996, the United Express Flight 5925 collided on landing at Quincy with another Beechcraft, a private King Air, that was taking off from an intersecting runway. All occupants of both planes, twelve on board the 5925 and two on board the King Air, were killed as a result.
A flood in June 2008 submerged much of Quincy's riverfront and low-lying regions not protected by the bluffs. Record Mississippi River levels occurred on June 22, 2008. The Red Cross accepted donations for Quincy and other communities in Adams County, as natural disaster funds were depleted in 2010.
Quincy has been twice recognized as an All-America City and is a participant in the Tree City USA program. In the fall of 2010, Forbes Magazine listed Quincy as the eighth "Best Small City To Raise A Family."

A central site in the district is the Dick Brothers Brewery Buildings, which were constructed in 1857 and rivaled many larger breweries. The lager tunnel system and natural aquifer can still be found underground. Although the brewery survived Prohibition by bottling water and other beverages, slow modernization efforts forced the brewery into bankruptcy. However, the buildings remain and are being renovated for public use and commercial space. Other examples of rich German-influence in Quincy can also be seen in the many brick homes within the district.
Francis Hall of Quincy University is another example of German influence in the city's structures.
Other than the South Side, Maine Street and the East End are popular strips where Quincy's rich architectural history is displayed. Once housing some of Quincy's elite, many of the homes in these regions are influenced mainly by Victorian schools.

Today, the Newcomb residence functions as the Quincy Museum and was once featured on the cover of National Geographic as "one of the most architecturally significant corners in the United States." There are many organizations in the town that continue to oversee renovations to structures, such as the Historical Society of Quincy & Adams County, and some residents allow for tours of their 19th Century homes.
There is also a significant Mediterranean influence to Quincy with the Villa Kathrine and B'nai Sholom Temple. In 1900, Quincy resident W. George Metz commissioned George Behrensmeyer to design a Moroccan-style home overlooking the river. It included a harem, courtyard, and reflecting pool. Today, the Villa Kathrine functions as the visitor's center. The Temple B'nai Sholom is another structure that was heavily influenced by the Moorish revival in the United States.

Illinois Route 57 branches south from U.S. 24 downtown and passes Quincy's Civic Center on its way to Interstate 172 southeast of the city. Illinois 96 also serves as the Great River Road, which follows the path of the Mississippi River. Eastbound U.S. 24 crosses the Mississippi River from Missouri on the Quincy Memorial Bridge, while westbound traffic uses the newer Bayview Bridge. Bayview bridge was constructed in 1986, but was not built as a four-lane bridge because of budget cuts, as the cable suspension made it unaffordable to build a four-lane bridge. Other groups claimed that business in the downtown part of Quincy would decline if the Memorial bridge was shut down.
