Adrian, city, seat (1838) of Lenawee county, southeastern Michigan, U.S., on the River Raisin, 40 miles (65 km) southwest of Ann Arbor. Addison J. Comstock settled the site in 1826 as Logan and renamed it in 1828 for the Roman emperor Hadrian (the H was dropped in 1838). With his father, Darius, Comstock built the Erie and Kalamazoo Railroad (1833–36, the first west of New York state) connecting Adrian and Toledo, Ohio (some 30 miles [50 km] southeast); its cars were horse-drawn until replaced by a locomotive in 1837. Originally an agricultural centre, the city has acquired some light industry (notably the manufacture of auto parts and aluminum, plastics, and wood products). The Michigan Department of Corrections, which operates two prisons near Adrian, has been an important employer since the late 1980s. Adrian College was founded in 1859. The Adrian Dominican Sisters, a Roman Catholic religious congregation that ministers throughout the United States and Canada and in several overseas countries, is based in Adrian and sponsors several institutions there, including Siena Heights University (1919) and St. Joseph Academy (1896). Lake Hudson Recreation Area is about 12 miles (20 km) to the southwest. Inc. village, 1836; city, 1853. Pop. (2000) 21,574; (2010) 21,133.
