Louisville is Kentucky's largest city and the 16th largest city in the U.S. It was founded in 1778 by George Rogers Clark and is named after King Louis XVI of France. Louisville lies in Jefferson County and sits on the Kentucky-Indiana border at the only natural obstacle in the Ohio River, the Falls of the Ohio. Louisville is the home of the Kentucky Derby, the most widely watched event in American horse racing. Louisville, Kentucky is home to several major corporations, including UPS International, Yum (owners of Kentucky Fried Chicken, Pizza Hut, Taco Bell and A & W Restaurants), Brown and Williamson Tobacco, Papa John's Pizza, and Hillerich & Bradsby (known for Louisville Slugger baseball bats).
