city, seat (1836) of Racine county, southeastern Wisconsin, U.S. It lies along Lake Michigan (Michigan, Lake) at the mouth of the Root River, about 25 miles (40 km) south of Milwaukee. Miami and Potawatomi Indians were early inhabitants of the region. Founded in 1834 as Port Gilbert by Gilbert Knapp, a lake captain, it adopted its present name, which was derived from the French word for “root,” in 1841. The improvement of its harbour in the 1840s and the arrival of the railroad in the 1850s spurred the city's growth as an industrial and shipping centre. Danish immigrants settled the area in the 19th century.

Racine's economy is based on manufacturing, including chemical home and personal-care products, farm machinery, metal castings, transmissions and other power equipment, cleaning equipment, household appliances, and heat-transfer equipment; printing and publishing are also important. It is the site of the SC Johnson administration and research complex, designed by Frank Lloyd Wright (Wright, Frank Lloyd). Racine contains a campus of the Gateway Technical College (1911). The holdings of the Racine Art Museum (established in 1941 and reopened in a new building in 2003) include an extensive collection of American crafts. The city also has a free zoo and a history museum. Wind Point Lighthouse, built in 1880 and automated in 1964, is considered the oldest active lighthouse on Lake Michigan. Racine has a display commemorating a bank robbery in 1933 by John Dillinger (Dillinger, John) and his associates. Inc. village, 1841; city, 1848. Pop.
