As of 2019, the population was an estimated 30,479.Danville was founded in 1827 on 60 acres (240,000 m2) of land donated by Guy W. Smith and 20 acres (81,000 m2) 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.Danville became a major industrial city in the late 19th and early twentieth centuries. From the 1850s to the 1940s, Danville was an important coal mining area; some of the first open pit mining techniques were practiced here.
