Lake Geneva is a city in Walworth County, Wisconsin, USA. The population was 7,651 at the 2010 census. A resort city located on Geneva Lake, it is popular with tourists from metropolitan Chicago and Milwaukee.HistoryOriginally called "Muck-Suck" for a Potawatomi chief, the city was later named Geneva after the town of Geneva, New York, located on Seneca Lake, to which early settler John Brink saw a resemblance. Geneva, to avoid confusion with the nearby town of Geneva, Illinois, was renamed Lake Geneva; later the lake was renamed Geneva Lake.Railroad access from Chicago made the area a popular summer retreat for the barons of wealth in lumber, cattle, oil, steel, cement, manufacturing, and durable goods , with mansions and large homes such as Stone Manor and Black Point built on the lake from the 1850s, through the heyday of the Roaring 20s, and up to the present day. The city was then known as "The Newport of the West." In the early automobile era, the city hosted the first modern drive-in motel designed by Frank Lloyd Wright, and later during Prohibition smaller lake towns around the area became a haven for Al Capone and other mobsters.
