The flag of Illinois

Illinois (/ˌɪlɪˈnɔɪ/ IL-in-OY) is a state in the Midwestern region of the United States. It borders Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-most land area. Its capital is Springfield.

Present-day Illinois was inhabited by Indigenous cultures for thousands of years. The French were the first Europeans to arrive, settling near the Mississippi and Illinois River in the 17th century as part of the sprawling colony of New France. Following U.S. independence in 1783, American settlers began arriving from Kentucky via the Ohio River. Illinois was part of the United States' oldest territory, the Northwest Territory, and in 1818 it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany and Sweden. In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network facilitated trade, commerce, and settlement, making the state a transportation hub for the nation. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large Black community, particularly in Chicago, which became a leading cultural, economic, and population center; its metropolitan area, informally referred to as Chicagoland, holds about 65% of the state's 12.8 million residents.

Two World Heritage Sites are in Illinois, the ancient Cahokia Mounds, and part of the Wright architecture site. Major centers of learning include the University of Chicago, University of Illinois, and Northwestern University. A wide variety of protected areas seek to conserve Illinois' natural and cultural resources. Three U.S. presidents have been elected while residents of Illinois: Abraham Lincoln, Ulysses S. Grant, and Barack Obama; additionally, Ronald Reagan was born and raised in the state. Illinois honors Lincoln with its official state slogan Land of Lincoln. The state is the site of the Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the Barack Obama Presidential Center in Chicago.

Marcus Ward Lyon, Jr. in 1917 at Washington Biologists’ Field Club on Plummers Island

Marcus Ward Lyon, Jr. was an American mammalogist, bacteriologist, and pathologist. He was born into a military family at Rock Island Arsenal, and demonstrated an early interest in zoology by collecting local wildlife around his father's army posts. He graduated from Brown University in 1897, and continued his studies at George Washington University while working part-time at the United States National Museum (USNM). He received his Ph.D. from George Washington University in 1913. In 1919, he and his wife, Martha, moved to South Bend, Indiana to join a newly opened clinic. Prior to moving, Lyon had published many papers on mammalogy, both during and after his tenure at the USNM. In these papers, he had formally described six species, three genera, and one family. Once in South Bend, he began to publish medical studies, too, but continued his work in mammalogy, with a particular focus on the local fauna of Indiana. He published more than 160 papers during his career.
