Danville is a city in and the county seat of Vermilion County, Illinois. As of the 2010 census, its population was 33,027. As of 2019, the population was an estimated 30,479. History The area that is now Danville was once home to the Miami, Kickapoo, and Potawatomi tribes of Native Americans. Danville was founded in 1827 on of land donated by Guy W. Smith and donated by Dan W. Beckwith. The sale of lots was set for April 10, 1827 and advertised in newspapers in Indianapolis, Indiana and the state capital of Vandalia. The first post office was established in May of the same year in the house of Amos Williams, organizer of Vermilion and Edgar Counties and a prominent Danville citizen. Williams and Beckwith drew up the first plat map; the city was named after Dan Beckwith at Williams' suggestion, although Beckwith suggested the names "Williamsburg" and "Williamstown". Beckwith was born in Pennsylvania in 1795 and moved to Indiana as a young man; in 1819 he accompanied the first white explorers to the area where Danville later existed because of his interest in the salt springs of the Vermilion River. He died in 1835 of pneumonia contracted on a horseback ride back from Washington; he was 40 years old. In 1838 the Potawatomi Trail of Death camped and then passed through Danville. Four Potawatomi people died and were buried in Danville. In the mid-1800s Abraham Lincoln visited Danville over the course of approximately 18 years as he practiced law across the 8th Judicial Circuit. Danville was home to Ward Hill Lamon his law partner who later served as his bodyguard. Lincoln later gave a speech in his stocking feet from the balcony of Dr. William Fithian, a prominent Danville physician. The Fithian home is listed on the National Register of Historic Places and serves as the Vermilion County Museum.
